Two particles of the same mass m are moving in circular orbits because of force, given by `F(r)=(-16)/(r)-r^(3)` The first particle is at a distance r =1 , and the second, at r = 4. The best estimate for the ratio of kinetic energies of the first and the second particle is closet to :
If two charged particles of same mass and charge are describing circles in the same magnetic field with radii r_(1) and r_(2)(gt r_(1)) the speed of the first particle is … that of the second particle while the time period of the particle is …that of the second partilcle.
A particle of mass m lies at a distance r from the centre of earth. The force of attraction between the particle and earth as a function of distance is F(r ),
A particle moves in a circular orbit under the action of a central attractive force inversely proportional to the distance r . The speed of the particle is
Two satellites of same mass are launched in circular orbits at height of 2R and 3R respectively. The ration of kinetic energies is
Charged particle of charge q mass m moves in a circular path of radius r under the action of force F .The equivalent current is
Charged particle of charge q mass m moves in a circular path of radius r under the action of force F .The equivalent current is
Two particles of equal masses are revolving in circular paths of radii r_(1) and r_(2) respectively with the same speed. The ratio of their centripetal force is
IF a particle of mass m is moving in a horizontal circle of radius r with a centripetal force (-(K)/(r^(2))) , then its total energy is
