Given is:-
Charge on each sphere is
distance between the two spheres is d = 2a or
Now,
Part-1
As the system is in equilibrium all the forces satisfy one another therefore
The net force on each sphere is zero
Part - 2
the electro static force between the two charged particles is given by
by plugging all the values we get
which gives us
This is the electrostatic force which is experienced by each sphere
Now,
the free body diagram of all the forces is shown below:
Therefore
by subsituting all the values we get
In the right angle triangle sine (angle) = perpendicular / hypotenuse
which gives us
this is the value of Tension in each string
Part-3
Again from the free body diagram the weight of the sphere is
by plugging all the values we get
which gives us
