Two blocks are connected by a string as shown in the diagram. The upper block is hung by another string. A force $F$ applied on the upper string produces an acceleration of $2\,m/{s^2}$ in the upward direction in both the blocks. If $T$ and $T'$ be the tensions in the two parts of the string, then $T$ and $T'$
$T = 70.8N$ and $T' = 47.2N$
$T = 58.8N$ and $T' = 47.2N$
$T = 70.8N$ and $T' = 58.8N$
$T = 70.8N$ and $T' = 0$
A body of mass $1\, kg$ lies on smooth inclined plane. The body is given force $F = 10N$ horizontally as shown. The magnitude of net normal reaction on the body is
A block of mass $M$ is pulled along a horizontal frictionless surface by a rope of mass $m$. If a force $P$ is applied at the free end of the rope, the force exerted by the rope on the block will be
The tension in the string which connected the blocks as shown in the following figure ............ $ N$
A monkey is decending from the branch of a tree with constant acceleration. If the breaking strength is $75 \%$ of the weight of the monkey, the minimum acceleration with which monkey can slide down without breaking the branch
In which of the following cases is the contact force between $A$ and $B$ maximum $(m_A = m_B = 1 kg)$
