[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 $
