A) \[\frac{D}{2}\]
B) \[\frac{2D}{3}\]
C) \[\frac{4D}{3}\]
D) \[\frac{9D}{10}\]
Correct Answer: D
Solution :
Force will be zero at the point of zero intensity \[x=\frac{\sqrt{{{m}_{1}}}}{\sqrt{{{m}_{1}}}+\sqrt{{{m}_{2}}}}d\]\[=\frac{\sqrt{81M}}{\sqrt{81M}+\sqrt{M}}D=\frac{9}{10}D.\]You need to login to perform this action.
