Prove that equi- potential surfaces closer to the charge have stronger electric field strength.

Prove that equi- potential surfaces closer to the charge have stronger electric field strength.

How to find the potential difference between two points in a capacitor.Please explain with a example.

 

horizontal range of a projectile

The horizontal range of a projectile is fired at an angle of 15 degree is 50 metre. If it is fired with the same speed at an angle of 45 degree what will be its range?

Why does life exist?

From the standpoint of physics, there is one essential difference between living things and inanimate clumps of carbon atoms: The former tend to be much better at capturing energy from their environment and dissipating that energy as heat.

“When a group of atoms is driven by an external source of energy (like the sun or chemical fuel) and surrounded by a heat bath (like the ocean or atmosphere), it will often gradually restructure itself in order to dissipate increasingly more energy. This could mean that under certain conditions, matter inexorably acquires the key physical attribute associated with life.” says Jeremy England, a 31-year-old assistant professor at the Massachusetts Institute of Technology.

Motion under Gravity

A ball is thrown vertically upwards from a tower,strikes the ground after time t1.If it is thrown vertically downward with the same speed it strikes the ground after t2.If the ball is dropped from the top of the tower,after how much time it will strike the ground?
