Write condition of equilibrium when three force act on a particle.
A uniform rope of mass $M$ and length $L$ is fixed at its upper end vertically from a rigid support. Then the tension in the rope at the distance $l$ from the rigid support is $x$
A body of mass $m$ hangs at one end of a string of length $l$, the other end of which is fixed. It is given a horizontal velocity so that the string would just reach where it makes an angle of $60^o$ with the vertical. The tension in the string at mean position is
A mass of $2\, kg$ suspended with thread $AB$ (figure). Thread $CD$ of the same type is attached to the other end of $2\, kg$ mass. if the lower thread is pulled with a jerk, what happens ?
Which force act on body first action or reaction ?
