An ionfinite number of charges each q are placed in the x-axis at distances of 1,2,4,8 meter from the origin. If the charges are alternately positive and negative find the intensity of electric field at 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

A charge of 2C is placed on the x -axis at 1m from the origin along - ve x-axis.Infinite number of charges each of magnitude 2C are placed on x-axis at 1m,2m,4m,...from origin along + ve x -axis.The first charge is positive and alternate charges are of opposite in nature.The electric field intensity at the origin?

A number of particles each of mass 0.75kg are placed at distances 1m, 2m, 4m, 8m etc. from origin along positive X axis. the intensity of gravitational field at the origin will be -

A charge of magnitude 1C is placed at origin. Infinite number of charges placed on y-axis at coordinates of 1m, 2m, 4m, 8m,...... of magnitude 1 mu C . Then find force exerted by these charge on the charge placed at origin

An infinite number of charges, each of magnitude q, are placed along x-axis at x = 1m, 2m, 4m, 8m, 16m and so on but the consecutive charges are of opposite sign starting with +q at x = 1m. A point charge q_0 , kept at the origin, experiences a force of magnitude :

An infinite number of charges each equal to 4 muC are placed along X-axis at x = 1 m, x = 2 m, x = 4 m, x = 8 m and so on. Find the total force on a charge of 1C plaaced at the origin.
