A) \[4m\]
B) \[6m\]
C) \[1m\]
D) \[2m\]
Correct Answer: D
Solution :
[d] Spring constant \[=100\text{ }N/m\] Conserving energy, \[mg\,\left( x+2 \right)\sin 30{}^\circ =\frac{1}{2}K.{{(2)}^{2}}\] \[10\times 10\left( x+2 \right)\times \frac{1}{2}=\frac{1}{2}\times 100\times 4\] \[x+2=4\] \[x=2\text{ }m\]along the inclined surface.You need to login to perform this action.
