The electric filed lines on the left have twice the sepration on those on the right as shown in figure . If the magntiude of the filed at A is `40 Vm^(-1)` .what is the force on ` 20 mu C` charge kept at B ?

In Fig. the electric field lines on the left have twice the separation of those on the right. (a) If the magnitude of the field at A is 60 N/C, what is the magnitude of the force on a protorn at A? (b) What is the magnitude of the field at B?

In the electric field shown in figure, the electric field lines on the left have twice the separation as that between those on the right. If the magnitudes of the fields at point A is 40NC^(-1) , calculate the force experienced by a proton placed at point A . Also find the magnitude of electric field at point B

The electric lines of force of two point charges are shown in fig. What is the value of the ratio q_(1)//q_(2) ?

Three equally charged objects are located as shown in the figure the electric force exerted by the object A on B is 3.0 xx 10^-6N . What is the net electric force on B?

A point charge q is moving with speed v perpendicular to magnetic field B as shown in figure. Explain what should be the magnitude and direction of the applied electric filed so that the net force acting on the charge is zero.
