SATHEE: Laws Of Motion Question 307

Laws Of Motion Question 307

Question: Three identical blocks of masses $m = 2 k g$ are drawn by a force $F = 10.2 N$ with an acceleration of $0.6 m s^{- 2}$ on a frictionless surface, then what is the tension (in N) in the string between the blocks B and C?

Options:

A) 92

B) 3.4

C) 4

D) 9.8

Show Answer

Answer:

Correct Answer: B

Solution:

[b] $F = (m + m + m) \times a$

$∴ a = \frac{10.2}{6} m / s^{2}$

$∴ T_{2} = m a = 2 \times \frac{10.2}{6} = 3.4 N$
