Question

Three blocks of masses m1 = 1 kg, m2 = 2 kg, m3 = 3 kg are attached to each other by thin wires on a frictionless horizontal plane. A horizontal force of F = 3 N is applying toward the right side on the block of mass m3. What is the tension T12 (in N) in the wire connecting the blocks of masses m1 and m2?

Answer 1

Answer:

0.5 N

Explanation:

Tension T12 = $\frac{m_1}{m_1+m_2+m_3} \times F$ = $\frac{1}{1+2+3} \times 3$ = 0.5 N
