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