Two masses $M$ and $m$ are connected by a weightless string. They are pulled by a force $F$ on a frictionless horizontal surface. The tension in the string will be
$\frac{{FM}}{{m + M}}$
$\frac{F}{{M + m}}$
$\frac{{FM}}{m}$
$\frac{{Fm}}{{M + m}}$
Write condition of equilibrium when three force act on a particle.
A book is lying on the table. What is the angle between the action of the book on the table and the reaction of the table on the book?
Two equal heavy spheres, each of radius $r$, are in equilibrium within a smooth cup of radius $3 r$. The ratio of reaction between the cup and one sphere and that between the two sphere is
Three weights $W, 2W$ and $3W$ are connected to identical springs suspended from a rigid horizontal rod. The assembly of the rod and the weights fall freely. The positions of the weights from the rod are such that
When body is at rest or it is in uniform motion, no force act on it.
