A unit positive charge has to be brought from infinity to a midpoint between two charges \(20 \mu \mathrm{C}\) and \(10 \mu \mathrm{C}\) separated by a distance of \(50 \mathrm{~m}\). How much work will be required?
- A \(10.8 \times 10^4 \mathrm{~J}\)
- B \(10.8 \times 10^3 \mathrm{~J}\)
- C \(1.08 \times 10^6 \mathrm{~J}\)
- D \(0.54 \times 10^5 \mathrm{~J}\)
Answer & Solution
Correct Answer
(B) \(10.8 \times 10^3 \mathrm{~J}\)
Step-by-step Solution
Detailed explanation
Given that, two charges \(q_1\) and \(q_2\) separated by \(d=50 \mathrm{~m}, q_1=20 \mu \mathrm{C}\) and \(q_2=10 \mu \mathrm{C}\) Work done in bringing \(q=1 \mathrm{C}\) from infinite to point \(M\) \(W=q V\) where, \(V\) be the electric potential at \(M\) due to charges…
