(a)
The energy expended in transferring
(a)
Explanation of Solution
Given:
The electric field intensity
The first point
The second point
The magnitude of the charge
Calculation:
The energy expended to transfer the charge is equal to the work done to move the charge.
Calculate the work done
Thus, the energy expended to transfer
(b)
The energy expended in transferring
(b)
Explanation of Solution
Given:
The electric field intensity
The first point
The second point
The magnitude of the charge
Calculation:
Calculate the work done
Thus, the energy expended to transfer
(c)
The energy expended in transferring
(c)
Explanation of Solution
Given:
The electric field intensity
The first point
Calculation:
Calculate the work done
Thus, the energy expended to transfer
(d)
The energy expended in transferring
(d)
Explanation of Solution
Given:
The electric field intensity
The first point
The second point
The magnitude of the charge
Calculation:
Since the electrostatic force is conservative, the path of integration is immaterial.
Suppose the charge follow the path to from point
Calculate the work done
Thus, the energy expended to transfer
