COMEDK · Physics · 17. Electrostatics
The work done in carrying a charge \(q\) once round a circle of radius \(r\) with a charge \(Q\) at the centre is
- A \(\frac{q Q}{4 \pi \varepsilon_{0} r}\)
- B \(\frac{q Q}{4 \pi \varepsilon_{0}^{2} r^{2}}\)
- C \(\frac{q Q}{4 \pi \varepsilon_{0} r^{2}}\)
- D None of these
Answer & Solution
Correct Answer
(D) None of these
Step-by-step Solution
Detailed explanation
According to given situation of charges, electrostatic force works which is conservative in nature i.e., work done depends on initial and final position only. Here, initial and final position coincide, hence work done will be zero.
