A 5.0-C charge is 10m from a -2.0-C charge. The electrostatic force on the positive charge is
a. 9.0 x 10 N toward the negative charge
b. 9.0 × 108 N away from the negative charge
c. 9.0 x 10 N toward the negative charge
d. 9.0 x 10 N away from the negative charge
e. none of these

The electrostatic force away from the negative charge is

(b) is correct option.

Explanation:

Given that,

First charge = 5.0 C

Second charge = -2.0 C

Distance = 10 m

We need to calculate the electrostatic force on the positive charge

Using formula of electrostatic force

Where, q₁ = first charge

q₂= second charge

r = distance

Put the value into the formula

The electrostatic force away from the negative charge.

Hence, The electrostatic force away from the negative charge is

because growing process had stoped after 4-5 year
