Three blocks are connected by massless strings on a frictionless inclined plane of \(30^{\circ}\) as shown in the figure. A force of \(104 \mathrm{~N}\) is applied upward along the incline to mass \(m_3\) causing an upward motion of the blocks. What is the acceleration of the blocks? (Assume, acceleration due to gravity, \(g=10 \mathrm{~m} / \mathrm{s}^2\) )
- A \(6.0 \mathrm{~m} / \mathrm{s}^2\)
- B \(4.5 \mathrm{~m} / \mathrm{s}^2\)
- C \(3.0 \mathrm{~m} / \mathrm{s}^2\)
- D \(1.5 \mathrm{~m} / \mathrm{s}^2\)
Answer & Solution
Correct Answer
(D) \(1.5 \mathrm{~m} / \mathrm{s}^2\)
Step-by-step Solution
Detailed explanation
The given situation is shown in the figure below, If the system moves upward with acceleration \(a \mathrm{~m} / \mathrm{s}^2\) on the application of \(104 \mathrm{~N}\), then the equation of motion for \(8 \mathrm{~kg}\) block is…
