13.4 x 10 raise to power - 19 C

Explanation:

. The distance moved by a charge in the direction of a uniform electric field is d = 1.8 cm = 0.018 m

. The uniform electric field is E = 214 N/M

, The decrease in electrical potential energy is d (P. E) = 51.63 x 10 raise to power - 19 J

Let the magnitude of the charge of the moving particle be q

which is given by the equation

d (P. E) = qEd

51.63 x 10 power - 19 = q (214) (0.018)

51.63 x 10 power - 19 = 3.852q

by making q the formular,

q = 13.4 x 10 power - 19 C
