Question

7. two charges q₁=4μc and q₂=-7μc are by 5m. calculate the electric potential at point a. (Physics subject)

Answer 1

V = K Q/r

V = V1 +V2 to c

V1 = KQ1/r1

V2 = KQ2/r2

Use + sign for Q1 and - sign for Q2

r1 and r2 are distances of Q1 and Q2 from point where potential is to be calculated

K = 9*10⁹

Remember to Change μc to c

Unit of V is Volt
