MCQ
Mass m2 is hanged using a uniform string whose other end is attached to a mass m1 . A string connects m1 to ground as shown in figure. Tension in this string is
- AZero
- B$m_1 g$
- C$m _2 g$
- ✓$\left(m_2-m_1\right) g$
✓
Answer
Correct option: D.
$\left(m_2-m_1\right) g$
(D) $\left(m_2-m_1\right) g$
$\begin{array}{l}T+m_1 g=m_2 g \\ T=\left(m_2-m_1\right) g\end{array}$
$\begin{array}{l}T+m_1 g=m_2 g \\ T=\left(m_2-m_1\right) g\end{array}$
