Two equally charged tiny spheres of mass 1.0 g are placed 2.0 cm apart. when released, they begin to accelerate away from each other at 414 m/s2. what is the magnitude of the charge on each sphere, assuming only that the electric force is present?

Charge,

Explanation:

It is given that,

Mass of spheres, m = 1 g = 0.001 kg

Distance between spheres, r = 2 cm = 0.02 m

Acceleration when they released,

We need to find the magnitude of the charge on each sphere. The electric force is given by :

Also, F = ma

So, the magnitude of charge on each spheres is . Hence, this is the required solution.                                        

a longitudinal wave moves energy that is to the direction of the wave’s movement. - true

adding a(n) to an electric circuit would increase the magnetic field around a wire;

b. solenoid

a solenoid is a type of electromagnet whose purpose is to generate a controlled magnetic field.

if the purpose of the solenoid is instead to impede changes in the electric current, a solenoid can be more specifically classified as an inductor rather than an electromagnet.
