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=

i think it because equal matrices have equal dimensions, only square matrices can be symmetric. for all indices and . every square diagonal matrix is symmetric, since all off-diagonal elements are zero. in linear algebra, a real symmetric matrix represents a self-adjoint operator over a real inner product space.
