Question

A ball weighing 100g is to be located within 0.1 angstrum.what is the uncertainty in its velocity?

​

Answer 1

Answer:

0.527547m/s

Explanation:

According to Heisenberg's uncertainity principle "It is impossible to measure or calculate exactly , both the position and momentum of an object."

The formula of uncertainity principle is given by:

delta (x) * delta (v)=h/4*3.14

 where delta (x): is uncertainity in position or change in position

             delta (v): is uncertainity in velocity or change in position

Given : m=100g = 0.1kg

                  Since 1kg=1000g;

x=0.1 angstrom = 10^-11 mt

                  Since 1 angstrom= 1×10^-11

Placing the value in the formula given above:

(10^-11)* delta(v)=(6.626*10^-11)/ 4*3.14

delta(v)=(6.626 * 10^-11)/(4*3.14*10^-11)

           =0.527547m/s
