Physics Newton's Laws of Motion Tension and Tension Force Single Correct MCQ
Published on: September 12, 2026

Three blocks of masses m_{1}, m_{2} and n_3 are connected by massless strings as shown on a frictionless table. They are pulled with a force \(T_3 = 40 \mathrm{N}\) . If \(m_1 = 10\,\text{kg}, m_2 = 6\,\text{kg}\) and \(m_3 = 4 \, \mathrm{kg}\) , the tension T_2 will be

A
20 N
B
40 N
C
10 N
D
32 N

The correct answer is:
D

\(T_2 = (m_1 + m_2) \times \frac{T_3}{m_1 + m_2 + m_3} = \frac{(10 + 6) \times 40}{20}\) \(= 32 \, \mathrm{N}\)
