Question

A charged cloud system produces an electric field in the air near Earth's surface. A particle of charge -2.2 x 10-9 C is acted on by a downward electrostatic force of 3.1 x 10-6 N when placed in this field. (a) What is the magnitude of the electric field? (b) What is the magnitude of the electrostatic force on a proton placed in this field? (c) What is the gravitational force on the proton? (d) What is the ratio of the electrostatic force to the gravitational force in this case?

*JUST NEED PART C*

answers for:

a)1409N/C

b)2.25E-16N

d)1.37E10

Explanation / Answer

Part C)

Gravitational Force is the weight

W = mg

W = (1.67 X 10^-27)(9.8)

W = 1.64 X 10^-26
