A charge Q is placed at the centre of circle of radius 10 cm . Find the work done in a moving charge between any two points lying on the are of circle.
- A \(k Q q J\)
- B \(0.1 kQ q J\)
- C \(0.5 kQ q J\)
- D 0 J
Answer & Solution
Correct Answer
(D) 0 J
Step-by-step Solution
Detailed explanation
(D)
\(\begin{array}{l} W =q\left(V_{ B }- V _{ A }\right) \\ W =0\left(\because V_{ B }= V _{ A }\right)\end{array}\)
\(\begin{array}{l} W =q\left(V_{ B }- V _{ A }\right) \\ W =0\left(\because V_{ B }= V _{ A }\right)\end{array}\)
