In the arrangement shown in the figure, work done by the string on the block of mass \(0.36 \mathrm{~kg}\) during the first second after the blocks are released from state of rest is (Ignore friction and mass of the string.)
(Acceleration due to gravity, \(g\) \(=10 \mathrm{~ms}^{-2}\))

  1. A \(8 \mathrm{~J}\)
  2. B \(4 \mathrm{~J}\)
  3. C \(12 \mathrm{~J}\)
  4. D \(2 \mathrm{~J}\)
Verified Solution

Answer & Solution

Correct Answer

(A) \(8 \mathrm{~J}\)

Step-by-step Solution

Detailed explanation

According to the question, Given, mass of block \(1, m_1=0.36 \mathrm{~kg}\) mass of block \(2, m_2=0.72 \mathrm{~kg}\) and acceleration due to gravity, \(g=10 \mathrm{~m} / \mathrm{s}^2\) Now, Dynamic equation of block \(m_1\left(m_2 > m_1\right)\).…
