A metal ball that weighs 0.1 kg and has a charge of 2 C is moving horizontally with a constant speed of 2 m / s? 3

A metal ball weighing 0.1 kg and a charge of 2 C is moving horizontally with it.

Permanent speed equal to 2 m / s, alone at a height of 0.5 m. There is a ball

Sweeta positions gravity and uniform vertical electric field.

If you assume that the acceleration is §Ã یا or if gravity is g = 10 m / s © © CORRECT then you are claiming that or

The pit of the electric field worships the sphere with its true unity

A) 2 N / F

B) 0 N / F

C) 0.5 N / F

D) 0.2 N / F

Answer: What is the solution?

In a constant motion, I mean it's balanced, logo:

Weight = felt.

Weight = 0.1 * 10 = 1

Feltric = q * E = 2 * electric field

Therefore, 1 = 2 * E => E = 0.5 N / c

many years!

This is the constant velocity that leads to the fact that for Agem re or Corpo àz z ... is equal to electric .. then the two will be the same.

P = Fe

Fe = m * g Fe = 0.1 * 10 Fe = 1N

E = Fe / q

E = 1/2 E = 0.5 N / C.
