You measure two quantities as $ A=1.0 \mathrm{~m} \pm 0.2 \mathrm{~m} $, $ B=2.0 . \mathrm{m} \pm 0.2 \mathrm{~m} $. We should report correct value for $ \sqrt{A B} $ as

A

$ 1.4 \mathrm{~m} \pm 0.4 \mathrm{~m} $

B

$ 1.41 \mathrm{~m} \pm 0.15 \mathrm{~m} $

C

$ 1.4 \mathrm{~m} \pm 0.3 \mathrm{~m} $

An ideal massless spring $ S $ can be compressed 1 m by a force of 100 N in equilibrium. The same spring is placed at the bottom of a frictionless inclined plane inclined at $ 30^{\circ} $ to the horizontal. A 10 kg block $ M $ is released from rest at the top of the incline and is brought to rest momentarily after compressing the spring by 2 m . If $ g=10 \mathrm{~m} / \mathrm{s}^{2} $, what is the speed of mass just before it touches the spring?

A

$ \sqrt{20} \mathrm{~m} / \mathrm{s} $

B

$ \sqrt{30} \mathrm{~m} / \mathrm{s} $

C

$ \sqrt{10} \mathrm{~m} / \mathrm{s} $

D

$ \sqrt{40} \mathrm{~m} / \mathrm{s} $
