Physics And Measurement Question 221

Question: The density of a material in CGS system of unit is $4 g / c m^{3}$ . In a system of units in which unit of length is 10 cm and unit of mass is 100 g, the value of density of material will be

Options:

A) 0.4

B) 40

C) 400

D) 0.04

Show Answer

Answer:

Correct Answer: B

Solution:

[b] In CGS system, $d = 4 \frac{g}{c m^{3}}$

The unit of mass is 1 00g and unit of length is 10 cm, so $d e n s i t y = \frac{4 (\frac{100 g}{100})}{{(\frac{10}{10} c m)}^{3}} = \frac{(\frac{4}{100})}{{(\frac{1}{10})}^{3}} \frac{(100 g)}{{(10 c m)}^{3}}$

$= \frac{4}{100} \times {(10)}^{3} . \frac{100 g}{{(10 c m)}^{3}} = 40 u n i t$
