Q. A pressure of $10^{6}$ dyne $cm ^{-2}$ is equivalent to
Physical World, Units and Measurements
A
$10^{5} Nm ^{-2}$
0%
B
$10^{4} Nm ^{-2}$
33%
C
$10^6 \,Nm^{-2}$
33%
D
$10^{7} \, Nm^{-2}$
33%
Solution:
1 Newton $=10^{5}$ dyne and $1\, m =100\, cm$
$10^{6}$ dyne $cm ^{-2}=10^{6} \times 10^{-5} N \times\left(10^{-2} m \right)^{2}=10^{5} Nm ^{-2}$
