SATHEE: Physics And Measurement Question 222

Physics And Measurement Question 222

Question: Young’s modulus of steel is $1.9 \times 10^{11} N / m^{2}$ . When expressed in CGS units of $n e / c m^{2}$ , it will be equal to ( $(1 N = 10^{5} d y n e, 1 m^{2} = 10^{4} c m^{2})$

Options:

A) $1.9 \times 10^{10}$

B) $1.9 \times 10^{11}$

C) $1.9 \times 10^{12}$

D) $1.9 \times 10^{13}$

Show Answer

Answer:

Correct Answer: C

Solution:

[c] It is given that Young’s modulus (Y) is, $Y = 1.9 \times 10^{11} N / m^{2}$

$1 N = 10^{5} d y n e$

$S o, Y = 1.9 \times 10^{11} \times 10^{5} d y n e / m^{2}$

Convert meter to centimeter $∵ 1 m = 100 c m$

$Y = 1.9 \times 10^{11} \times 10^{5} d y n e / {(100)}^{2} c m^{2}$

$= 1.9 \times 10^{12} d y n e / c m^{2}$
