What is the force two changed objects exert on one another if they are 9 meters apart and one has a charge of 2.5 x 10^-6 C and the second has a charge 0f 4.5 x 10^-7 C

The force exerted between the two charges is 0.0001248N

Explanation:

we will be using Columb's law to solve this problem.

Columb's law explains that the Force between two charged bodies is directly proportional to the product of their charges and inversely proportional to the square of the distance between them.

Mathematically,

WHere K = constant of proportionality =

The force exerted between the two charges is 0.0001248N

energy stored in the capacitor= 9.72 x 10⁻⁴ j

explanation:

the energy stored in the capacitor is given by

e= 1/2 c v²

e= energy stored

c= capacitance= 1.5 µc= 1.5 x 10⁻⁶f

v= potential difference=36 v

so energy stored= e= 1/2 (1.5 x 10⁻⁶) (36)²

energy stored= 9.72 x 10⁻⁴j
