Two particles
Two particles, each of mass m and charge q, are attached to the two ends of a light rigid rod of length 2R. The rod is rotated at constant angular speed about a perpendicular axis passing through its centre. The ratio of the magnitudes of the magnetic moment of the system and its angular momentum about the centre of the rod is

Two bodies start moving in the same straight line at the same instant of time from the same origin. The first body moves with a constant velocity of 40ms^-1, and the second starts from rest with a constant acceleration of 4ms^-2.Find the time that elapses before the second catches the first body. Find the also the greatest distance between them prior to it and time at which this occurs

A police jeep ,
approaching a right-angled intersection from the north ,
is chasing a speeding car that has turned the corner and is now moving straight east. When the jeep is 0.6km north of the intersection and the car is 0.8km to the east ,
the police determine with radar that the distance between them and the car is increasing at 20kmh^-1. If the jeep is moving at 60kmh^-1 at the instant of measurement ,

Two particles ,
what is the speed of the car? ,
Two particles, 1 and 2 move with constant velocities v 1 and v 2 along two mutually perpendicular straight lines towards the intersection point O. At the moment t=0 the particles were located at the distance l 1 and l 2 from the point O. How soon will the distance between the particles become the smallest? What is it equal to?
