Explanation:
Distance of second charge from origin d
d =
= 1.374 m
electric potential energy of system of charge
= 9 x 10⁹ x 3.2 x 3.2 x 10⁻¹² / 1.374
67.07 x 10⁻³ J
This energy will be converted into kinetic energy
1/2 x m v² = 67 x 10⁻³
v² = 2 x 67 x 10⁻³ / m
= 2 x 67 x 10⁻³/ 2.63 x 10⁻³
v = 7.13 m /s
b ) kinetic energy at this point = 67/4 x 10⁻³
= 16.75 x 10⁻³
Potential energy = 67x10⁻³ - 16.75 x 10⁻³ = 50.75 x 10⁻³
If r be the required distance
9 x 10⁹ x 3.2 x 3.2 x 10⁻¹² / r = 50.75 x 10⁻³
r = 1.87 m
