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 What is the magnitude of the charge on each sphere, assuming only that the electric force is present? (k = 1/4πε0 = 9.0 × 109 N ∙ m2/C2)

Explanation:

We are given that

Mass of charged tine spheres=m=1 g=

1 kg=1000g

The distance between charged tine spheres=r=2 cm=

1 m=100 cm

Acceleration =

Let q be the charge on each sphere.

The electric force between two charged particle

Using the formula

The force between two charged tiny spheres=

According to  Newton's second law , the net force

Hence, the magnitude of charge on each tiny sphere=

the working equation for the angular size is the product of the physical size and 360 degrees divided by the product of two pi and distance from earth. the minimum size would be 0.559 degrees while the maximum size would be 0.49 degrees.
