Electrostatic potential due to a system of charges

Calculate the electrostatic potential energy for a system of three point charges q placed at the corners of an equilateral triangle of side ‘a’.

Find the electric potential energy of the system of charges. (a)

Two point charges q and -2q are kept 'd' distance apart. Find the location of the point relative to charge q at which potential due to the system of charges is zero.

The electrostatic potential due to the charge configuration at point P as shown in figure for bltlta is

The side of the cube is 'l' and point charges are kept at each corner as shown in diagram. Interaction electrostatic potential energy of all the charges is:

Assertion(A): In bringing an electron towards a proton electrostatic potential energy of the system increases Reason (R ) :Potential due to proton is positive.

The electrostatic field due to a point charge depends on the distance r as (l//r^(2)) . Similarly, indicates how each of the following quantities depends on r : (a) Intensity of light from a point source (b) Electrostatic potential due to a point source (c) Electrostatic potential due to a distance r from the center of a charged metallic sphere of radius R (r lt R) .
