A charge of 0.05 C moves a negative charge upward due to a 2 N force exerted by an electric field. What is the
magnitude and direction of the electric field?
0.03 N upward
0.03 N downward
40 N upward
40 N downward

Electric field at this position of charge is 40 N/C and upwards in the direction of force

Explanation:

As we know that the force on a charge due to electric field is given as

here we know that

F = 2 N

q = 0.05 C

now from above formula

here we have

+15-35=-20

going in opposite directions
