Two blocks of masses 10 kg and 30 kg are placed on the same straight line with coordinates (0,0) cm and (x, 0) cm respectively. The block of 10 kg is…
Two blocks of masses $\displaystyle 10$ kg and $\displaystyle 30$ kg are placed on the same straight line with coordinates $\displaystyle (0,0) \mathrm{cm}$ and $\displaystyle (x, 0) \mathrm{cm}$ respectively. The block of $\displaystyle 10$ kg is moved on the same line through a distance of $\displaystyle 6$ cm towards the other block. The distance through which the block of $\displaystyle 30$ kg must be moved to keep the position of centre of mass of the system unchanged is :
Official answer
(3)
$\displaystyle 2$ cm towards the $\displaystyle 10$ kg block
