A trolley of mass 300 kg carrying a sandbag of 25 kg is moving uniformly with a speed of 27 km//h on a frictionless track. After a while, sand starts leaking out of a hole on the floor of the trolley at the rate of 0.05 kg s^-1 . What is the speed of the trolley after the entire sand bag is empty ?

There is a circular path around a sports field. Sonia takes 18 minutes to drive one round of the field, while Ravi takes 12 minutes for the same. Suppose they both start at the same point and at the same time, and go in the same direction. After how many minutes will they meet again at the starting point ?

Figure shows two identical capacitors C_1 and C_2 each of 1 mu F capacitance connected to a battery of 6 V. initially switch S is closed. After sometime S is left open and dielectric slab of dielectric constant k = 3 are inserted to fill completely the space between the plates of the two capacitors. How will the potential difference between the plates of the capacitors be affected after the slabs are inserted?
