The electric intensity, at points near a charged conducting surface is sigma//epsilon_0Using this equation derive an expression for the electric intensity due to a conducting sphere of radius rata point on it’s surface, if it gains a total charge q

Answer»

SOLUTION :E NEAR the surface of the SPHERE =`sigma/epsilon_0`But `sigma="charge"/"AREA"=q/(4pir^2)E=q/(epsilon_0xx4pir^2)=1/(4piepsilon_0)xxq/r^2`
