A) \[\text{9}\text{.8},\text{9}\text{.8}\]
B) \[\text{4}\text{.9},\text{9}\text{.8}\]
C) \[\text{9}\text{.8},\text{4}\text{.9}\]
D) \[\text{4}\text{.9},\text{4}\text{.9}\]
Correct Answer: D
Solution :
The acceleration in bodies sliding on a frictionless inclined plane does not depend upon the mass of the body. It is given by\[g\sin \theta \]. Thus acceleration in both the bodies must be same. Now there are only two such options, [a] and [d]. But acceleration of a body on an inclined plane cannot be equal to\[g\]. So the correct option has to be [d]. It can also be calculated easily by the formula\[g\sin \theta =9.8\times \frac{1}{2}=\mathbf{4}\cdot \mathbf{9}\]
