A particle of mass m is constrained to move along a straight line. A and B are two fixed points on the line at a separation of L. When the particle is at some point P, between A and B, it is acted upon by two forces vecF_(1)=((6mg)/(L))vecPA " and " vecF_(2)=((3mg)/(L))vecPB At time t=0, the particle is projected from A toward B with a speed of sqrt(gL) . At what time 't' will the particle reach at B for the first time ?

Two particles of equal mass m and charge t are placed at a distance 16 cm. They do no experience any force. The value of q/m is……..

A particle of mass 'm' moves on a horizont smooth line AB of length 'a' such that when particle is at any general point P on the line two force act on it. A force (mg(AP))/(a) towards A and another force (2mg(BP))/(a) towards B . If the force acting towards A stops acting when the particle is nearest to B then find the velocity with which it crosses point B.
