A block of weight $W$ is suspended by a string of fixed length. The ends of the string are held at various positions as shown in the figures below. In which case, if any, is the magnitude of the tension along the string largest?

An ideal string is passing over a smooth pulley as shown. Two blocks $m_1$ and $m_2$ are connected at the ends of the string. If $m_1=1 \mathrm{kg}$ and tension in the string is $10 \mathrm{N}$, mass $m_2$ is equal to $\left(g=10 \mathrm{m} {\mathrm{s}}^{-2}\right)$

A point mass $m$ is suspended from a light thread of length $\mathcal{l},$ fixed at $O$, is whirled in a horizontal circle at constant speed as shown. From your point of view, stationary with respect to the mass, the forces on the mass are:

A small object, suspended by a string, rotates with constant speed, in a horizontal circle as shown in the figure. Point $O$ is at the centre of the circle. Neglect air drag. Which one of the following statement is correct?

In the figure shown the acceleration of $A$is,${\overrightarrow{a}}_A=15\hat{\mathrm{i}}+15\hat{\mathrm{j}}$ then the acceleration of $B$ is ($A$ remains in contact with $B$)
