Derive an expression for electric field due to a uniformly charged spherical shell. i) at a point outside the shell

Using this law, derive an expression for electric field due to thin uniformly charged shell.

Obtain an expression for potential due to a point charge

Derive an expression for the magnetic field intensity produced at a point lying along the axis of a circular coil carrying current.

One can determine the direction of electric field around a stationary charge with the help of electric field lines. Br Consider a spherical shell of radius .R. is uni formly charged with charge .+q.. By using Gauss.s theorem, find the electric field intensity at a point .p.. br i) Outside the spherical shell. br ii) Inside this spherical shell

If the flux of the electric field through a closed surface is zero, then: (a)the electric field must be zero every-where on the surface (b)the total charge inside the surface must be zero (c)the electric field must be uniform throught the closed surface (d)the charge outside the surface must be zero

Electric field due to dipole at any point on the equatorial plane is having direction

Intensity of electric field is a vector quantity. Define intensity of electric field at a point.
