The position - time graphs of two bodies A and B show in Which of these moves faster ? Explain.

A graph of x versus t is shown in fig. choose corredt alternatives from below.

A straight segment OC(of length L meter) of a circuit carrying a current I amp is placed along the x- axis ( fig.). Two infinitely long straight wires A and B , each extending from z = -oo to +oo , are fixed at y = -a meter and y = +a meter respectively, as shown in the figure. If the wires A and B each carry a current I amp into the plane of the paper, obtain the expression for the force acting on the segment OC. What will be the force on OC if the current in the wire B is reversed?

A test charge q is moved without acceleration from A to C along the path from the point A to B and then from B to C in electric field as shown in fig. At which point( of the two) is the electric potential more and why?

There are two factories located one at place P and the other at place Q. From these locations, a certain commodity is to be delivered to each of the three depots situated at A, B and C. The weekly requirements of the depots are respectively 5,5 and 4 units of the commodity while the production capacity of the factories at P and Q are respectively 8 and 6 units. The cost of transportation per unit is given below : How many units should be transported from each factory to each depot in order that the transportable cost is minimum. When will be the minimum transportation cost?

A medical company has factories at two places. A and B. From these places, supply at P, Q and R. The monthly requirements of the agencies are respectively 40, 40 and 50 packets of the medicines, while the production capacity of the factories A and B, are 60 and 70 packets respectively. The transportation cost per packet from the factories to the agencies are given below : How many packets from each factory be transported to each agency so that the cost of transportation is minimum? Also find the minimum cost.

Direction. In the follwing questions, a statement of assertion is followed by a statement of reason. While answering a question, you are required to choose the correct are out of the given four responses and mark it as (A). If both assertion and reason are true and reason is the correct explanation of the assertion, (B) if both assertion and reason are true but reason is not correct explanation of the assertion. (C) if assertion is true, but reason if false, (D) if both assertion and reason are false Assertion : In a transformer, the number of turns in the primary and secondary coils are 500 and 1,250 respectively. If the current in primary coil is 2 A, then the current in secondary coil will be 5 A. Reason : The current in secondary coil is given by I _ s = Ip xx (N_s)/(N_P)
