Question

An electric charge of 1 microcoulomb is affected by an electric field of intensity 1000 newtons per coulomb at a point, then this point is a meter away from it by a distance

Answer 1

r = 3 m

Step-by-step explanation:

Given that,

Charge,
`q=1\ mu C`

Electric field at a point,
`E=1000\ N/C`

We need to find the distance away from it. We know that electric field at point r is given by :

`E=(kq)/(r^2)\\\\r=\sqrt{(kq)/(E)} \\\\r=\sqrt{(9* 10^9* 10^(-6))/(1000)} \\\\r=3\ m`

So, the required distance is 3 m.
