If the uncertainity in the position of an electron is `10^(-10) m`, then the value of uncertainity in its momentum (in `kg-ms^(-1)`) will be

Options

A. `3.33 xx 10^(-24)`
B. `1.03 xx 10^(-24)`
C. `6.6 xx 10^(-24)`
D. `6.6 xx 10^(-20)`

Answer

2

Explanation

`Deltap=(h)/(Deltax)=(1.034xx10^(-34))/(10^(-10))=1.034xx10^(-24)kg-ms^(-1).`
