If a negative charge is released in a uniform electric field, it will move.

A. from low to high potnetial
B. in ciruclar motion
C. in the direction of the electric field
D. from high to low potential
E. In a direction perpendicular to the electric field

A. from low to high potential

Explanation:

When a negative charge is released in a uniform electric field, the electric force will have a different sign than the field, so it will move in the opposite direction to the field. An uniform electric field is always directed from high to low potential. Thus, negative charges move from low to high potential.

energy stored in the capacitor= 9.72 x 10⁻⁴ j

explanation:

the energy stored in the capacitor is given by

e= 1/2 c v²

e= energy stored

c= capacitance= 1.5 µc= 1.5 x 10⁻⁶f

v= potential difference=36 v

so energy stored= e= 1/2 (1.5 x 10⁻⁶) (36)²

energy stored= 9.72 x 10⁻⁴j
