Two small, positively charged spheres have a combined charge of 5.0 x 10 -5 c. if each sphere is repelled from the other by an electrostatic force of 1.0 n when the spheres are 2.0 m apart, what is the charge, in micro-coulomb, on the sphere with the smaller charge?

Explanation:

It is given that,

Let q₁ and q₂ are two small positively charged spheres such that,

.............(1)

Force of repulsion between the spheres, F = 1 N

Distance between spheres, d = 2 m

We need to find the charge on the sphere with the smaller charge. The force is given by :

............(2)

On solving the system of equation (1) and (2) using graph we get,

So, the charge on the smaller sphere is 11.6 micro coulombs. Hence, this is the required solution.

a, c, d, e are all applying about success strategies.

force is mass*acceleration.

we have a very small mass: 11.4*0.001 kg

if we want 0.035n of force, we need an acceleration:

0.035 = 11.4*0.001*a

a = 0.035/(11.4*0.001) m/s^2
