Physics · Electric potential and its calculation for a point charge, electric dipole and system of charges
A particle with a charge of 3 coulombs is taken from a point at a potential of 5
A particle with a charge of 3 coulombs is taken from a point at a potential of 50 V to another point at a potential of \( 120 \mathrm{V} \) Calculate the work done.
- A. 23.33 J
- B. 2.4 J
- C. 210
- D. 40 J
Step-by-step solution
Work done W = qΔV = 3 C × (120 V - 50 V) = 3 × 70 = 210 J.
