A) \[\frac{1}{\sqrt{m}}\]
B) m
C) \[\frac{1}{m}\]
D) \[\sqrt{m}\]
Correct Answer: A
Solution :
[a] As per Newtons second law, |
\[F=ma\Rightarrow a\frac{F}{m}\] |
Using equation of motion, |
\[{{v}^{2}}={{u}^{2}}+2as\] |
\[\Rightarrow \ \ \ \ \ {{v}^{2}}=2\left( \ \frac{F}{m} \right)s\] (\[\because \]u=0) |
\[v\propto \frac{1}{\sqrt{m}}\] |
