The sphere’s Electric potential energy is 1.6*J
Given,
q=6. 5 µc, V=240 v,
We know that sphere’s Electric potential energy(E) = qV=6.5*=1.6*
J
The configuration of a certain set of point charges within a given system is connected with the potential energy (measured in joules) known as electric potential energy, which is a product of conservative Coulomb forces. Two crucial factors—its inherent electric charge and its position in relation to other electrically charged objects—can determine whether an object has electric potential energy.
In systems with time-varying electric fields, the potential energy is referred to as "electric potential energy," but in systems with time-invariant electric fields, the potential energy is referred to as "electrostatic potential energy."
A tiny sphere carrying a charge of 6. 5 µc sits in an electric field, at a point where the electric potential is 240 v. what is the sphere’s potential energy?

Answer:
Compression of the spring: 0.18 m (downward)
Explanation:
The forces acting on the block of wood are:
- The force of gravity, acting downward, of magnitude , where m = 5.32 kg is the mass of the block and
is the acceleration due to gravity
- The force exerted by the spring, downward, of magnitude , where
is the spring constant and
is the elongation of the spring
- The buoyant force, upward, of magnitude , where
is the water density and V the volume of the block
Since the block is in equilibrium, the net force is zero, so we can write
(1)
We have to find the volume of the block first. We have:
m = 5.32 kg (mass)
(wood density)
So, the volume is
So now we can re-arrange eq.(1) to find the elongation of the spring, x:
So, the spring is compressed by 0.18 m.
