Correct answer is B
Density of H2O = 1gcm3
Density x pressure = constant
D1 x P1 = D2 x P2
13.6 x 0.76 = 1 x P2
P2 = 10m

Correct answer is E
Efficiency = M.A x 100%
= \(\frac{200}{50}\) x \(\frac{1}{5}\) x 100
= 80%

Correct answer is B
Let unstretched length = L
e1 = 14 - L and e2 = 16 - L
Using, \(\frac{m_1}{e_1}\) = \(\frac{m_2}{e_2}\)
\(\frac{20}{14 - L}\) = \(\frac{30}{16 - L}\)
L = 10cm
