Boojho and Paheli were given one mirror each by their teacher. Boojho found his image to be erect and of the same size whereas Paheli found her image erect and smaller in size. This means that the mirrors of Boojho and Paheli are, respectively

In a test Arun scored 20 % and failed by 10 marks Bala scored 40% in the same test and obtained 10 marks more than the pass mark. Find the maximum marks.

Once, Paheli visited a tailor shop and brought home some cuttings of fabric to study their properties. She took two pieces and found that one of the pieces were shrinking when it was burnt with a candle. However the other did not shrink on burning. Can you help her to find out which of the two was a cotton fabric and which a silk fabric?

In the circuit shown all live resistors have the same volue 200 oms and each cell has an emf 3 volts. Find the open circuit voltage and the short circuit current for the terminals A and B.

A test tube consists of a hemisphere and a cylinder of the same radius.The volume of the water required to fill the whole tube is (5159)/(6)cm^(3) and (4235)/(6)cm^(3) of water required to fill the tube to a level which is 4cm below the top of the tube.Find the radius of the tube and the length of its cylindrical part.

Two point charges q and - q are located at points (0 , 0 , - a ) and (0 , 0 , a) respectively : (a) Find the electrostatic potential at (0 , 0 , z) and ( x , y , 0). (b) How much work is done in moving a small test charge from the point (5 , 0 , 0 , ) to (-7 , 0 , 0 ) along the x - axis ? (c) How would your answer change if the path of the test charge between the same points is not along the x axis but along any other random path ? (d) If the above point charges are now placed in the same position in a uniform external electric field vecE , what would be the potential energy of the charge system in its orientation of unstable equilibrium ? Justify your answer in each case .

A siphon is used to drain water (density =rho ) from a wide tank. The inlet and outlet mouth of the siphon are at the same horizontal level and the highest point of the siphon tube is at a height H from the mouth of the tube. Height of water in the tank above the tube mouth is h (see fig). Atmospheric pressure is P_(0) . (a) Will the water drain out in this siphon? if yes, at what speed (V)? (b) Find pressure at the top of the siphon tube (call in P) (c) Find pressure just inside the left mouth of the tube. (d) If left part of the tube is slightly cut short, without disturbing anything else, what effect it will have on V and P? (e) If the right end of the tube is lowered by adding more lenght of tube, it was observed that flow stops when lenght of right limb of the tube becomes H_(0) . Find H_(0) .

If Boojho covers a certain distance in one hour and Paheli covers the same distance in two hours, who travels in a higher speed?
