A) \[7\times {{10}^{3}}N/m\]
B) \[7\times {{10}^{2}}N/m\]
C) \[7\times {{10}^{-2}}N/m\]
D) \[70\,\,N/m\]
Correct Answer: C
Solution :
The unit dyne/cm is CGS system of unit. The CGS unit of force is dyne and SI unit is Newton. Also there are \[{{10}^{5}}\] dynes in one newton and \[100cm\] in\[1cm\]. \[\therefore \] \[\frac{70\,\,dynes}{cm}=\frac{70\times {{10}^{-5}}}{{{10}^{-2}}}=7\times {{10}^{-2}}N/m\]You need to login to perform this action.
