Figure shows the field lines of a point negative charge. In going from B to A, the kinetic energy of a small negative charge will.
A
Increase
B
Decrease
C
Remains constant
D
Data insufficient
Answer
Decrease
Explanation
Solution
: Due to force of repulsion on the negative charge, velocity decreases and hence the kinetic energy decreases in going from B to A.
