A charged particle with a mass of 4.0 x 10-3kg and a charge of 65.0x10-4C is travelling at 1750 km/hr. If it enters a 32,500 N/C electric field, how much of a change in voltage is necessary to bring it to a halt? What must the sign of the voltage change be?

Homework Answers

Answer #1

given

mass m = 4.0 x 10-3 kg

charge of q = 65.0 x 10-4 C

v = 1750 km/hr

= 486 m/sec

E = 32,500 N/C electric field,

change in voltage is V = ?

we have equation 1/2 m v2 = q V

0.5 x 4.0 x 10-3 x 4862 = 65 x 10-4 x V

V = 0.5 x 4.0 x 10-3 x 4862 / 65 x 10-4

V = 72675.692 volts

so the change in voltage is V = 72675.692 volts

using V = W / Q

the charge must be positive.
