If `10^(9)` electrons move out of a body to another body evergy second, how much time is required to get a total charge of 1 C on the other body?

Text Solution

Verified by Experts

In one second `10^(9)` electrons move out of the body therefore the charge given out in one seconds is `1.6 xx10^(-19) xx 10^(9) C=1.6 xx10^(-10) C` the time required to accumulate a charge of 1 c can then be estimeated to be from a body from which `10^(9)` elelctons move out every second we will unit for many practical purposes it is however also important to know what is roughtly the number of a cubic piece of coper of side 1 cm contains about `2.5 xx10^(24)` electrons

The contact force exerted by a body A on another body B is equal to the normal force between the, bodies. We conclude that a) the surfaces must be frictionless b) the force of friction between the bodies is zero c) the magnitude of normal force equals that of friction d) the bodies may be rough but they don't slip on each other.

A force of 20 N acts on a body of mass 5kg at rest. What is the acceleration of the body? What is its velocity after 5 seconds if the same force acts? After 5 seconds if the force ceases to act how will the body move?
