Question

When 10^12 electrons are received from a
neutral metal sphere. The charge on the
sphere becomes.
(a) 0.16uc
(b) -0.16uc
(c) 0.32uc
(d) -0.32 uc​

Answer 1

Given ,

Number of electrons = 10¹²

As we know that , the charge on a body is an integral multiples of electrons present on it

$\boxed{ \tt{Charge \: (q) = ne}}$

Thus ,

q = 1.6 × 10^(-19) × 10¹²

q = 1.6 × 10^(-7)

q = 0.16 × 10^(-6)

q = 0.16 uc

Hence ,

• The charge on the sphere is 0.16 uc
