Question

Which of the following statements is true concerning the magnitude of the electric field at a point in space? Two imaginary spherical surfaces of radius R and 2R respectively surround a positive point charge Q located at the center of the concentric spheres. When compared to the number of field lines N_1 going through the sphere of radius R, the number of electric field lines N_2 going through the sphere of radius 2R is A uniform electric field, with a magnitude of 600 N/C, is directed parallel to the positive x-axis If the potential at x = 3.0 m is 1,000 V, what is the potential at x = 2.0 m?

Explanation / Answer

1) option (e)

2) N2=N1 (option (d))

3)  The electric field equals the gradient, or first derivative versus position, so
E = - deltaV / deltaX
600 N/C = - (1000volts - V1) / (3m - 2m)
so V1 = 1600 volts (option (c))
