The acceleration of $10\,kg$ block when $F =30\,N$
$1$
$3$
$2$
None
The maximum "$F$" which will not cause motion of any of the blocks $............\,N$
A coin is dropped in a lift. It takes time $t_1$ to reach the floor when lift is stationary. It takes time $t_2$ when lift is moving up with constant acceleration, then
In the arrangement shown in figure, pulley is smooth and massles and all the strings are light let $F_1$ be the force exerted on the pulley in case $(i)$ and $F_2$ the force in case $(ii)$. Then
A bomb of mass $1 \,kg$ initially at rest, explodes and breaks into three fragments of masses in the ratio $1: 1: 3$. The two pieces of equal mass fly off perpendicular to each other with a speed $15 \,m / s$ each. The speed of heavier fragment is ........... $m / s$
Find the acceleration of $3\,kg$ mass when acceleration of $2\,kg$ mass is $2\,ms ^{-2}$ as shown in figure.
