The position of both an electron and a helium atom is known within 
and the momentum of the electron is known within 
. The minimum uncertainty in the measurement of the momentum of the helium atom is
A
B
C
D
Text Solution
Verified by ExpertsThe correct answer is:
D
The product of uncertainties in the position and the momentum of a sub atomic particle 
. Since 
is same for electron and helium so 
must be same for both the particle i.e. 
(given).
