Answer:
250 kgm/s
Explanation:
To calculate momentum, simply take the product of the mass and velocity.
The speed of the electron when it is 10.0 cm from the +3.00 nC charge is 30×
meters per second.
Given :
q=3.00 nC
r=distance=10 c.m
we apply formula
Velocity of electron =qd
=10×
×3=30×
m/sec
The speed of electricity is determined by what you mean by the term "electricity." This is a broad term that essentially means "all things relating to electric charge." I'll presume we're talking about an electrical charge current moving through a metal wire, like the power cord of a light. Electrical currents passing through metal wires have three different velocities, all of which are physically significant:
The velocity of electron drift.
