Find the work done by some external force in moving a charge q=4 muC from infinity to a point, where electric potential is 10^(4)V

A charge q=2muC is moved by same external force from infinity to a point where electric potential is 10^(4) V .Calculate the work done by external force.

Two points charges are located on the x-axis, q_1=-1muC at x=0 and q_2=+1muc at x=1m . a. Find the work that must be done by an external force to bring a third point charge q_3=+1muC from infinity to x=2m . b. Find the total potential energy of the system of three charges.

Which of the following statement(s) is/are correct? If the electric field due to a point charge varies as r^(-2.5) instead of r^(-2),then the Gauss law will still be valid. The Gauss law can be used to calculate the field distribution around an electric dipole. If he electric field between two point charges is zero somewhere,then the sign of the two charges is the same. The work done by the external force is moving a unit positive charge from point A at potential "V_(A)" to point B at potential "V_(B)" is,(V_(B)-V_(A))

The work require to displace charge q from infinity to given point is W, then electric potential at that point is

A charge Q is placed at the origin. The electric potential due to this charge at a given point in space is v . The work done by an external force in bringing another charge q from infinity up to the point is
