Consider the lines of force as shown in the figure. Two unit positive charges are kept at points A and B.
A. Charge at A will suffer greater force
B. Charge at B will suffer greater force
C. Force at both points will be same but non-zero
D. Force at both points will be the same
Answer:B
Consider the lines of force as shown in the figure. Two unit positive charges are kept at points A and B.
A. Charge at A will suffer greater force B. Charge at B will suffer greater force C. Force at both points will be same but non-zero D. Force at both points will be the same
Explanation: More number of field lines cross unit cross-section area at point B. Therefore electric field intensity will be more at point B than that of point A. Thus a unit positive charge will face greater force at point B than point A. So we can conclude that field intensity will be greater where the field lines are dense.
