Two 1.0 kg masses are 1.0 m apart (center to center) on a frictionless table. each has a +10μc of charge. a) what is the magnitude of the electric force on one of the masses? b) what is the initial acceleration of one of the masses if it is released and allowed to move?

(a). The electric force is 0.9 N.

(b). The acceleration is 0.9 m/s²

Explanation:

Given that,

Mass = 1.0 kg

Distance = 1.0 m

Charge = 10 μC

(a). We need to calculate the electric force

Using formula of electric force

Put the value into the formula

(b). We need to calculate the acceleration

Using newton's second law

Put the value into the formula

Hence, (a). The electric force is 0.9 N.

(b). The acceleration is 0.9 m/s²

convex lenses are thicker at the middle. rays of light that pass through the lens are brought closer together (they converge). a convex lens is a converging lens. when parallel rays of light pass through a convex lens the refracted rays converge at one point called the principal focus.
