The uncertainty in the position of a mov...

The uncertainty in the position of a moving bullet of mass `10 g` is `10^-5 m`. Calculate the uncertainty in its velocity.

Text Solution

Verified by Experts

According to uncerainty principle,
`Deltax.m Delta upsilon =(h)/(4 pi) or Delta upsilon =(h)/(4 pi m Delta x),h=6.626xx10^(-34)kgm^(2)s^(-1) , m=10g =10^(-2)kg`,
`Deltax=10^(-5)m , Delta upsilon=((6.626xx10^(-34)kg m^(2)s^(-1)))/((4xx3.143)xx(10^(-2)kg)xx(10^(-5)m))=5.27 xx 10^(-28) ms^(-1)`.
