Question

A 5C charge experiences a constant force of 2000 N when moved between two points separated by a distance of 2 cm in an uniform electric field. The potential difference between these two points is–

• A. 8 V
• B. 200 V
• C. 800 V
• D. 20, 000 V

Answer 1

Answer: (A)

8 V

Answer 2

E = $\frac { F } { q }$ = $\frac { 2000 } { 5 }$ = 400 N/C

d = 2cm = 2 × 10^–2 m

V = Ed = 400 × 2 × 10^–2 = 8 Volt
