[EAMCET 2001]

Options:

A) 0.036

B) 0.36

C) 3.6

D) 36

Show Answer

Answer:

Correct Answer: C

Solution:

$ n _{2}=n _{1}{{( \frac{M _{1}}{M _{2}} )}^{1}}{{( \frac{L _{1}}{L _{2}} )}^{1}}{{( \frac{T}{T _{2}} )}^{-2}} $ = $ 100{{( \frac{gm}{kg} )}^{1}}{{( \frac{cm}{m} )}^{1}}{{( \frac{\sec }{min} )}^{-2}} $ = $ 100{{( \frac{gm}{10^{3}gm} )}^{1}}{{( \frac{cm}{10^{2}cm} )}^{1}}{{( \frac{\sec }{60\sec } )}^{-2}} $

n2 = $ \frac{3600}{10^{3}}=3.6 $
