The electric field in a region is directed outward and is proportional to the distance r from the origin, Taking the electric potential at origin to be zero,

The electric field in a region is directed outward and is proportional to the distance r from the origin. Taking the electric potential at the origin to be zero

the electric field inside a sphere which carries a charge density proportional to the distance from the origin p=alpha r ( alpha is a constant) is :

If the electric field in a given region is zero,the potential at that region

Electric field in a region of space is radially outward from origin and varies with distance 'r' from origin as E = kr. Find the charge enclosed in a sphere of radius 'a' centred at origin.

Electric field in a region of space is radially outward from origin and varies with distance 'r' from origin as E = kr. Find the charge enclosed in a sphere of radius 'a' centred at origin.

The electric field in a region is radially outward and at a point is given by E=250" r V"//"m" (where r is the distance of the point from origin). Calculate the charge contained in a sphere of radius 20 cm centred at the origin

The electric field in a region is radially outward and varies with distance r as E = 250 r ( volt per square metre).Calculate the charge contained in a sphere of radius 0.2 m centere at the origin.
