A charg e ` + 10^9 C` is located at the oergin in free space `&` another charge ` Q` at ` (2,0,0)` . If the X-component of the electric field at (3,1,1) is zero , calculate the value of `Q`, Is the Y-component zero at (3,1,1) ?

A charge q = (-2 xx 10^(+)) is placed at (1 m, 2m, 3m). There is a point P = l^(2) - 3m, 4 m) Component of electric field along x-axis at point would be

A graph of the x-component of the electric field as a function of x in a region of space is shown in the figure. They y and z-components of the electric field are zero in this region. The electric potential at the origin is 10 V. The value of x for which potential is zero is

Two point charges Q and -3Q are placed at some distance apart. If the electric field at the location of Q is E, then field at the location of -3Q is

Two charge Q_(1)=18muC and Q_(2)=-2 mu C are separated by a distance R, and Q_(1) is on the left of Q_(2) . The distance of the point where the net electric field is zero is

Two charge Q_(1)=18muC and Q_(2)=-2 mu C are separted by a distance R, and Q_(1) is on the left off Q_(2) . The distance of the point where the net electric field is zero is
