SATHEE: Laws Of Motion Question 417

Laws Of Motion Question 417

Question: Three blocks are placed at rest on a smooth inclined plane with force acting on $m_{1}$ parallel to the inclined plane. Find the contact force between $m_{2}$ and $m_{3}$ :

Options:

A) $\frac{(m_{1} + m_{2} + m_{3}) F}{m_{3}}$

B) $\frac{m_{3} F}{m_{1} + m_{2} + m_{3}}$

C) $F - (m_{1} + m_{2}) g$

D) F

Show Answer

Answer:

Correct Answer: B

Solution:

[b]

$F = (m_{1} + m_{2} + m_{3}) g \sin θ$ …(i)

$N = m_{3} g \sin θ$ ..(ii)

Dividing Eq. (ii) by Eq. (i), we get

$N = \frac{m_{3} F}{m_{1} + m_{2} + m_{3}}$
