The charge on 1 microgram (g) electron will be......(mass of an electron = `9.11 xx 10^(-31)` kg)

A

`1.76 xx 10^(-3)` C

B

`176 xx 10^(0)` C

C

`176 xx 10^(3)` C

D

`176 xx 10^(5)` C

Text Solution

Verified by Experts

The correct Answer is:
B
Charge on `9.11 xx 10^(-31) kg = 1.6 xx 10^(-19)` C
Charge on `10^(-9)` kg - ?
`Q=(1.6 xx 10^(-19) xx 10^(-9))/(9.11 xx 10^(-31))`
`therefore Q = 176 C`
