Ten charges having charge 1 `mu` C 8 `mu` C 27 `mu` C ....1000 `mu` C are placed on the x-axis with co-ordinates x=1m 2m 3m 4m....10m .The net electric field intensity at the origin is

Four charges of 1mu C, 2mu C, 3mu C and -6 mu C are placed one at each corner of the square of side 1 m . The square lies in the x-y plane with its centre at the origin.

An infinite number of charges, each of charge 1 mu C are placed on the x -axis with co-ordinates x=1,2,4,8….oo If a charge of 1C is kept at the origin, then what is the net force action on 1C charge

If the linear charge density of a cylinder is 4 mu C m^(-6) ,then electric field intensity at point 3.6 cm from axis is :

An infinite number of charges, each equal to Q=10 mu C are placed along the x-axis at x=1, 3, 9 …..m . Calculate the magnitude of electric field at x=0 if the consecutive charge have opposite signs.
