Question

Which of the following statements is true concerning the magnitude of the electric field at a point in space? It is a measure of the total charge on the object. It is a measure of the electric force on any charged object. It is a measure of the ratio of the charge on an object to its mass. It is a measure of the electric force per unit mass on a test charge. It is a measure of the electric force per unit charge on a test charge. 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 N1 going through the sphere of radius R, the number of electric field lines N2 going through the sphere of radius 2R is 4N2 = N1 2N2 = N1 N2 = 4N1 N2 = N1 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? -200 V 400 V 1600 V 2200 V

Explanation / Answer

the force acting on a test charge in an electricfield determines magnitude of electric field at that point charge

E=F/q hence options b and e are right answers.....

2. electric field does not depend on radius hence option D is right answer
