Answer:
Q = - 256 X 10⁻⁷ C .
Explanation:
Electric field due to a charge Q at a distance d from the center is given by the expression
E = k Q /d² Where k is a constant and it is equal to 9 x 10⁹
Put the given value in the equation
9 x 10² =
Q =
Q = - 256 X 10⁻⁷ C .
It will be negative in nature as the field is directed towards the center.
