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.

initial speed when it is dropped is 150 ft/s

now at the same moment the acceleration due to gravity is perpendicular to its velocity

so as we know that

now we have centripetal acceleration a = 32 ft/s^2 as its perpendicular to velocity

while tangential acceleration at the same moment will be zero

so

now radius of curvature is given as

so the radius of curvature just after it is dropped is 703.125 ft
