Question

small metal is fair carrying the charges + Q is located at the centre of a spherical cavity in a large and start matic metallic spherical shell write the charges on the inner and outer surface of the cell write the expression for the electric field at the point p 1​

Answer 1

Explanation:

+Q charge is present in the centre whichmeans that electric field lines will will come outwards from the inside of the sperical cavityand Also electric field at p1 will be:

E=F/Q0

=>E=(1/Q0)×(kQQ0)/r²

Here the value of k=1/4π€0

=>E=(1/4π€0)×(Q/r²)

This is the electric field applied by the Q on p1

Here Q0=p1
