Question

An isolated conductor sphere of radius 0.1m placed
in vacuumed carrier apositive charge 0.1uc Find the
electeic intensity at a point at a distance 0.2 from the
centre of sphere​

Answer 1

$\huge{\underline{\tt{\green{Given-}}}}$

Radius = 0.1 m

charge = 0.1 $\mu$C

distance from the centre of the sphere = 0.2m

$\huge{\underline{\tt{\blue{Formula \ used-}}}}$

$E=\dfrac{1}{4\pi \mathcal{E}_0K}\dfrac{q}{r^2}$

$\huge{\underline{\tt{\red{Solution-}}}}$

$E= \dfrac{9\times 10^9\times 10^{-7}}{1\times0.2\times0.2}$

$E= 2.25\times 10^4 N/C$
