Question

-
The uncertainity in position of an electron & helium
atom are same. If the uncertainity in iromentum
for the electron is 32 x 10%, then the unceriarity
in momentum of helium atom will be
(1) 32 x 105
(2) 16 x 105
(3) 8 x 105
(4) None​

Answer 1

Explanation : According to uncertainty principle the product of uncertainty in position and uncertainty in momentum is constant for a particle. As, Δx = 1.0 nm for both electron and helium atom, so Δp is also same for both the particles.
