37- 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: Electric field density is represented by the closeness of the field lines. The lines are significantly closer and more dense at region B than at region A, meaning the electric field strength (and thus the force $F = qE$) is greater at position B.
38- Field lines due to a positive point charge are _______
a) Circular, Counter-Clockwise
b) Circular, Clockwise
c) Parallel, Uniform
d) Radial, Outward
Explanation: Electric field lines naturally emerge symmetrically and extend radially outward away from an isolated positive point charge.
