Question

Consider four equal charges q1,q2,q3and q4=q=+1microcouloumb located at four different points on a circle of radius 1m ,as shown in figure. Calculate total force acting on charge q1 due to all other charges

Answer 1

Answer:

ANSWER

Let x be the distance from 10μc where potential is zero

⇒0=xk(10μC)+20−xk(−20μC)

⇒0=x10−20−x20

⇒(20−x)10=20x

⇒20=3x

 ⇒x=320=6⋅67cm
