If uncertainty in position and momentum are both equal, then uncertainty in velocity is:

1. $\frac{1}{2\mathrm{m}}\sqrt{\frac{\mathrm{h}}{\mathrm{\pi }}}$

2. $\sqrt{\frac{\mathrm{h}}{2\mathrm{\pi }}}$

3. $\frac{1}{\mathrm{m}}\sqrt{\frac{\mathrm{h}}{\mathrm{\pi }}}$

4. $\frac{\mathrm{h}}{\mathrm{\pi }}$

 Assertion (A): It is impossible to determine the exact position and exact momentum of an electron simultaneously. Reason (R): The path of an electron in an atom is clearly defined.

 1 Both (A) and (R) are True and (R) is the correct explanation of (A). 2 Both (A) and (R) are True but (R) is not the correct explanation of (A). 3 (A) is True but (R) is False. 4 (A) is False but (R) is True.

The measurement of the electron position is associated with an uncertainty in momentum which is equal to 1x10-18 g cm s-1. The uncertainty in velocity of the electron will be:

(mass of an electron is 9 x 10-28 g)

1. 1 x 109 cm s-1

2. 1 x 106 cm s-1

3. 1 x 105 cm s-1

4. 1 x 1011 cm s-1
