Answer:
256 x 10³ Nm
Explanation:
Force on each of the charges of 8 C due to uniform electric field in x -y plane will be equal and opposite because one is positive charge and the other is negative charge. They will make a couple
Each of the forces of the couple will act in x - y plane and will be equal to
F = Q E = 8 X 8 X 10³
= 64 X 10³ N
Arm of the couple = 4 m
Moment of couple about z axis.
= 64 x 10³ x 4
= 256 x 10³ Nm.
