Is there any lower limit to the electric force between two
. particles placed at a separation of 1 cm?

What is reason behind producing electric force between two particles ?

Electric force between two protons is ...... times greater than gravitational force.

Coulombian force between two charges ………….

Which type of electric force acts between the proton and the electron?

A charges particles particle is kept in equilibrium in the electric field between the plates of millikan oil drop experiment. If the direction of the electric field between the plates is reversed, then calculate acceleration of the charged particle.

the coulombian force acting between two protons separated by a distance r is F, what would be the force acting between two alpha particles seperated by a distance 2r ?

A proton is 1836 times heavier than an electron. If the repulsive force between two protons is F for given distance, then the electric force between two electrons at same distance will be.........N.

How did Coulomb find the law of value of electric force between two point charges ?

A particle is acted upon by a force of constant magnitude which is always perpendicular to the velocity of the particle. The motion of the particle takes place in a plane. It follows that

A charge 3 coulomb experiences a force 300 N when placed in a uniform electric field. The potential difference between two points separated by a distance of 10 cm along the field line is:
