Question

Find the potential due to a charge of 3C at 1m away

Answer 1

Answer:

Explanation:

V = k q / r

  =  9*10^9  * 3 / 1

V = 27 * 10 ^9 V

Answer 2

Explanation:

V=kQ/r where k=9×10^9

Q=3C & r=1m

putting the values in the formula

V=9×10^9×3/1=2.7×10^10 volts

finally we get, potential at 1m away from 3C charge is 2.7×10^10 volts
