In a uniform electric field a charge of 3 C experiences a force of 3000 ~N . The potential difference between two points 1 ~cm apart along the electric line of force will be
Options
- A10 ~V
- B30 ~V
- C300 ~V
- D100 ~V
Correct answer
A. 10 ~V
Step-by-step solution
As E= F q = 3000 ~N 3 C =1000 NC ⁻¹ . d r=1 ~cm =10⁻² ~m d V=E(d r)=1000 10⁻²=10 ~V
