Question

3. When 10^14 electrons are removed from a neutral metal sphere, the charge on the sphere

becomes
Α. 32 με
Β. 16 με
C. -16 με
D. -32 με​

Answer 1

Β. 16 με

Step-by-step explanation:

Data provided in the question

Number of electrons removed = 10^14

And, the charge on one electron =
`1.6* 10^ {-19C}`

Based on the above information, the charged on the sphere is

Therefore when we remove the electrons

So, the equation would be

`10^(14) * 1.6 * 10^(-19 C)`

=
`1.6 * 10`

Therefore the same amount of the positive charged would be developed

Hence, the correct option is B.
