90 J of work is done to move an electric charge of magnitude 3 C from a place A , where potential is -10 V to another place B , where potential is ' V ₁ ' volt. The value of V ₁ is
Options
- A10 V
- B20 V
- C30 V
- D-40 V
Correct answer
B. 20 V
Step-by-step solution
aligned & W = q ~V & ~W = q ( ~V ₁- V _ A ) & W =3 [ ~V ₁-(-10) ] & 90 3 = V ₁+10 & ~V ₁=20 ~V aligned
