Boojho , Paheli and their firend Golu were provided with a test tube each containing China rose solution which was pink in colour .Boojho added two drops of solution 'A' in his test tube and got dark pink colour .Paheli added 2 drops of solution 'B' to her test tube and got green colour.Golu added 2 drops of solution 'C' but could not get any change in colour Suggest the possible cause for the variation in their results.

In the circuit shown in fig E_1 = 3 volts, E_2 = 2volts, E_3 = 1volt and R = r_1 = r_2= r_3= 1 ohm. (i) Find the potential difference between the points A and B and the currents through each branch. (ii) If r_2 is short circuited and the point A is connected to point B, find the current through E_1, E_2, E_3 and the resistor R.

Directions : In this section you have few short passages. After each passage, you will find some items based on the passage. First, read a passage and answer the items based on it. You are required to select your answers based on the contents of the passage and opinion of the author only. Passage I have always opposed the idea of dividing the world into the Orient and the Occident. It is, however, the tremendous industrial 'growth that has made the West what it is. I think the difference, say, between India and Europe in the 12th or 13th century Would not have been very great. Differences have been intensified by this process of industrialization which has promoted material well-being tremendously and which is destroying the life of the mind, which is in a process of deterioration, chiefly because the environment that has been created by it does not give time or opportunity to individuals to think. If the life of the mind is not encouraged, then inevitably civilization collapses. The author believes that the difference between India and Europe in the 12th or 13th century was not very great because

(a) Find potential difference between A and B and C . (b) Find potential difference across capacitor C . (i) Find ratio of energy stored in capacitors, C_(1) and (C_2) (ii) If battery of emf of 2E is short -circuited, find charge flown in battery of emf 4E .

A discharge tube contains helium at a low pressure. A large potential difference is applied across the tube. Consider a helium atom that has just been ionized due to the detachment of an atomic electron. Find the ratio of the distance travelled by the free electron to that by the positive ion in a short time dt after the ionization.

A rich merchant had collected many gold coins. He did not want anybody to know about them. One day, his wife asked, "How many gold coins do we have"?. After pausing a moment, he replied, "Well if I divide the coins into two unequal numbers, then 48 times the difference between the two numbers equals the difference between the squares of the two numbers". The wife looked puzzled. Can you help the merchant's wife by finding out how many gold coins the merchant has ?

Two capillaries of small cross section are connected as shown in the figure. The right tube has cross sectional radius R and left one has a radius of r (lt R) . The tube of radius R is very long where as the tube of radius r is of short length. Water is slowly poured in the right tube. Contact angle for the tube wall and water is theta = 0^(@) . Let h be the height difference between water surface in the right and left tube. Surface tension of water is T and its density is rho . (a) Find the value of h if the water surface in the left tube is found to be flat. (b) Find the maximum value of h for which water will not flow out of the left tube .
