12 j of work has to be done against an existion electric field to take a charge of 0.01 C from A to B. How much is th potential difference V_B V_A?

15 joule of work has to be done against an existing electric field to take a charge of 0.01 C from A to B. Then the potential difference (V_(B) - V_(A)) is :-

What is the magnitude and direction of the electric force on a -1.2 mu C charge at a point where the electric field is 2500 N/C and is directed along the +y axis.

Caleulate the electric field due to an electric dipole of length 10 cm having charges of 1 mu C at a point 12 cm from the centre of the dipole.

A particle having charge of 20muC and mass 20mug moves along as circle of radius 5cm under the action of a magnetif field B=0.1 tesla. When the particle is at P , uniform transverse electric field is switched on an it is found that the particle continues along the tangent with a uniform velocity. Find the electric field

A positively charged infinitely long cylinder has a radius of 0.1 m and surface charge density of 8.85xx10^(-12)C//m^(2) . What is the intensity of the electric field at a point on the surface of the cylinder, if the cylinder is kept in vacuum?
