Question

(a) Determine the direction of the electric field.

Answer: up or down.

(b) Determine the charge on the bead.

A positively charged bead having a mass of 1.00 g falls from rest in a vacuum from a height of 3.50 m in a uniform vertical electric field with a magnitude of The bead hits the ground at a speed of 22.0 m/s.

(a) Determine the direction of the electric field.

Answer: up or down.

(b) Determine the charge on the bead.

Round your answer to three significant figures. Take the acceleration of gravity to be

_____

3.00 × 10 " N/C

Explanation / Answer

Given that

mass m=1 g

electric field E=3*10^4 N/c

speed V=22 m/s

height h=3.5 m

basing on the concept of the intensity of electric field

now we find the charge on the bead

v^2-u^2=2qEh/m

22^2-0^2=2*q*3*10^4*3.5/10^-3

0.484=21*10^4 *q

charge q=2.305*10^-6 C
