Question

when 10 raised to 14 electrons are removed from a neutral metal sphere the charge on the sphere becomes

A. 16C
B. -16C
C. 32C
D. -32C

Answer 1

Given :

Number of electrons removed from the sphere = 10¹⁴ electrons

To Find :

The charge on the sphere = ?

Solution :

• Charge on the sphere (q) = ne

• By substituting the values in the formula

      q = ne

      q = 10¹⁴ × 1.6×10⁻¹⁹

      q = 1.6×10⁻⁶ C

      q = 1.6μC

 The charge on the sphere is  1.6μC
