Question

A bat used in sports of cricket is cut at the location of its centre of mass shown in the figure. Then

• A. the masses of both the pieces will be same
• B. mass of part II would be larger
• C. mass of part I would be larger
• D. mass of part I would be thrice the mass of part II

Answer 1

The correct option is B mass of part II would be larger

Let the two parts have masses $m_1$ and $m_2$ respectively and $1$ and $2$ be their centers of mass.

We have $m_1{x}_1-m_2{x}_2=O$
$\Rightarrow m_2=\frac{x_1}{x_2}{m}_1$
since $x_1>x_2\Rightarrow m_2>m_1$
