Answer:
The energy dissipated is
Explanation:
From the question we are told that
The distance covered at constant velocity d = 2 m
The velocity is
Generally at constant velocity the magnetic force on the bar is mathematically represented as
substituting values
The energy dissipated is mathematically evaluate as
substituting the value
To solve this problem we will apply the principles of energy conservation. The kinetic energy in the object must be maintained and transformed into the potential electrostatic energy. Therefore mathematically
Here,
m = mass (At this case of the proton)
v = Velocity
k = Coulomb's constant
= Charge of each object
r= Distance between them
Rearranging to find the second charge we have that
Replacing,
Therefore the charge on the sphere is 3.6531nC
