Please help me with this problem....

A ring of mass m free to slide on a fixed smooth horizontal wire is attached to one end of a string of length 60cm. The other end of the string is attached to a particle of mass 2m. The string and the particle are initially held at the same horizontal level with the string taut. If the system is now released, find the angular velocity of the string when it makes an angle of 60 degrees with the vertical.

Is it possible for a particle to describe a curved path if no force acts on it? Does your answer depend on the frame of reference chosen to view the particle ?
Actually particle CAN move without applying force depending on your frame of reference. Though we still use “pseudo-force” or ficticious forces to balance out the motion. Accelerated frames ...

2kg of gas at a pressure of 1.5 bar.occupies a volume of 2.5m cube.if this gas compresses isothermally to 1/3 times the initial volume.find temperature,work done,heat transfer.
As the pocess is isothermal chanege in Internal energy would be zero and hence temperature remains costant that is T. From ideal gas eqn. PV =nRT 1.5 * 2.5*1000 = 2000/32 * 0.0821 * T we...

If a cycle wheel of radius 4 m completes one revolution in two seconds, then acceleration of a point on the cycle wheel will be-(1)π^2m/s^2(2)2π^2m/s^2(3)4π^2m/s^2(4)8π^2m/s^2
angular velocity would be: w = theta/time = 2*pi/2 = pi rad accln. = w^R = > pi^2 * 4 = 4*pi^2 m/s^2.

Two charged particles are placed at a distance 1.0cm.what is the minimum possible magnitude of the electric force acting on each charge?
now F=KQq/R^2 LET Q=q=1e. F=K/R^2. F=9X10^9 X 100 X 100 . (K=9X10^9 & R=1cm=0.01) 9x10^13 is the minimum force which can be attractive or repulsive depending upon the nature of charges.

There is no air in space because there is no gravity to condense the molecules of gases found there into air . On Earth, gravity holds nitrogen, oxygen .there is no atmosphere also in space.
