The potential energy of a system of two particles separated by a distance r is given by U(r) = A/r, where A is a constant. Find the radial force F→r that each particle exerts on the other.
A system consists of N identical particles of mass m placed
rigidly on the vertices of a regular polygon with each side of
length l. If K₁ be the kinetic energy imparted to one of the
particles so that it just escapes the gravitational pull of the
system and thereafter kinetic energy K₂ is given by to the
adjacent particle to escape, then the difference (K₁-K₂) is
The 3D vector field F = -r/(Ir|^3) represents the force of gravity exerted by a mass located at the
origin. It is a conservative vector field, with potential function o = 1/ |rl. Calculate the work
done by gravity on an object moving along a path C from (0, 0, 3) to (0, 1, 0).
