Question
Two identical capacitors 1 and 2 are connected in series. The capacitor 2 contains a dielectric slab of constant K as shown. They are connected to a battery of emf V0 volts. The dielectric slab is then removed. Let Q1 and Q2 be the charge stored in the capacitors before removing the slab and Q1 ¢, and Q2 ¢ be the values after removing the slab. Then
Q 2 = ( K + 1 ) 2 
Q 2 = K + 1 2 K 
Q l = K 2
The correct answer is:

The sphere at P is given a downward velocity v0 and swings in a vertical plane at the end of a rope of l = 1 m attached to a support at O. The rope breaks at angle 30° from horizontal, knowing that it can withstand a maximum tension equal to three times the weight of the sphere. Then the value of v0 will be:
