sir...one doubt in problem follows
The earth has on electric charge that causes an electric field near its surface of the order of 100 vm-1.What is the surface density of charge on earth of earth is a conducting sphere? pls help me 2 solve it
Take earth as a conducting sphere of surface charge density (sigma)
Assume total charge that is spread on the surface is Now concentrated on the center. Find Electric field at the surface by usual equation
sir i have a doubt. please answer it,
"The escape velocity from the surface of earth is given by V=((2GM)^1/2)/R
were M is mass&R is the radius of earth.check the correctness of formula(using dimensions)
sir...one doubt in problem follows
*what will happen to the time period of a simple pendulum in a lift moving downwards?
what will be th angular velocity of a charge q moving in a eliptical path around another charge Q.
