How do you find the electric field on the y axis?
Answers and Replies. The E field due to one of the charges (the one at x=1.02) on the y-axis is given by your equation E=k*q/r^2. if you draw a line from your charge to the point on the y-axis, this E vector points in this direction.
What is the magnitude of electric field at the point P?
The electric field at point P caused by each charge is equal in magnitude, and both electric fields are in the same direction. are equal in magnitude and the same distance from the origin.
What is the formula for electric field magnitude?
E = F q test = k | Q | r 2 . This equation gives the magnitude of the electric field created by a point charge Q. The distance r in the denominator is the distance from the point charge, Q, or from the center of a spherical charge, to the point of interest.
Where is the electric field zero?
For unlike charges, the electric field is zero outside of the smaller magnitude charge. For like charges, the electric field will be zero closer to the smaller charge and will be along the line joining the two charges.
What is the magnitude of the electric field at point P due to the two fixed charges as shown *?
The magnitude of electric field at point P due to the system of two charges as shown in figure is (K = 4. Odda se answer: Kq 1202.
What is the magnitude of the electric field at a distance of 1.5 m from a point charge with Q 3.5 C?
Upon the distance between the charge and point p is 1.5 m, so 1.5 m square. Therefore, the magnitude of the electric field strength at point B is 1.4 into 10.
How do you find the net electric field at a point?
Strategy. We can find the electric field created by a point charge by using the equation E=kQr2 E = k Q r 2 .
Can electric field be negative?
An electric field can never be negative. An electric field is a force experienced by the charge divided by the magnitude of the charge. The magnitude of the charge is the modulus value of the charge.
What is the magnitude of the electric field at point P midway between the two charges?
The electric field midway between any two equal charges is zero no matter how far apart they are or what size their charges are.
What is the magnitude and direction of the electric force on an electron in a uniform electric field?
The magnitude of that force is going to be the charge times the electric field strength, and to that, it’s negative 1.602 times 10 to the minus 19 Coulombs charge in electron times 2,460 Newtons per Coulomb. This gives us 3.94 times 10 to the minus 16 Newtons directed West.
What is the magnitude of the electric field at a distance of 1.5 m from a point charge?
How do you find the magnitude and direction of an electric field?
Calculate the magnitude and direction of the electric field at a point A located at 5 cm from a point charge Q = +10 μC. k = 9 x 109 Nm2C−2, 1 μC = 10−6 C) The distance between point A and point charge Q (rA) = 5 cm = 0.05 m = 5 x 10-2 m
What is the direction of the electric field at point P?
If point P is to the left of Q1; the electric field generated by Q1 at the point P is to the left (away from Q1) and the electric field generated by Q2 at the point P to the right (towards Q1). The direction of the electric field is opposite so that the two electric fields eliminate each other so that the electric field strength at point P is zero.
What is the magnitude of the electric field from charge B?
Charge B is positive so that the direction of the electric field points away from charge B (to the left). We use the quadratic formula to determine a. The magnitude of the electric field is zero located at 8 cm from charge A or 12 cm from charge B.
What is an electric field at a distance?
If a point charge q ′ is at a distance r from the charge q then it will experience a force This is electric field at a distance r from a point charge q and r ^ is the unit vector along the direction of electric field. Above relation defining electric field at a distance r tels about both magnitude and direction of the field.
