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?

The co-ordinates of two points A and B are (-1, 4) and (5, 1) respectively. Find the co-ordinates of the point P, which lies on extended time AB such that it is three times as far from B as from A.

Two large flat parallel sheets A and B having a uniform charge density + sigma are held as shown in the figure. Graphically, represent the variation of electric field due to the two sheets as one moves from the point O to P.

A uniform but time-varying magnetic field B(t) exists with in a circular region of radius a and is directed in to the plane of the paper as shown in the figure. The magnitude of the induced electric field at the point P at a distance r from the centre of the circular region
