Two particles A and B are moving uniform...

Two particles A and B are moving uniformly in a plane in two concentric circles. The time period of rotation is `T_(A) = 8` minute and `T_(B) = 11` minute respectively for the two particles. At time`t = 0`, the two particles are on a straight line passing through the centre of the circles. The particles are rotating in same sense. Find the minimum time when the two particles will again fall on a straight line passing through the centre.
