Answer 2

Question -

Two unequal mass ${\sf m_1\: and \: m_2}$ are connected by a string which passes over a frictionless pulley as shown in fig. If ${\sf m_1 \: , m_2}$ and table are frictionless the acceleration of the masses.

Given :

• Two mass unequal ${\sf m_1 \: and m_2}$

To Find :

• Acceleration of the masses (a)

Solution :

Refer to the Attachment for Diagram.

T = Tension

$\implies{\sf T = m_2 a \: \: \:-(eq\: 1)}$

$\implies{\sf m_1g - T = m_1a \; \: \: (eq\:2) }$

From Equation 1 and Equation 2

$\implies{\sf m_1g - m_2a = m_1a}$

$\implies{\sf m_1g = m_1a + m_2a }$

$\implies{\sf m_1g = a(m_1+m_2)}$

$\implies{\bf a = \dfrac{m_1g}{m_1+m_2)}}$

Answer :

Option (A) ${\bf a = \dfrac{m_1g}{m_1+m_2}}$
