In which case will a rope have the greater tension : two men pull the ends of the rope with forces F equal in magnitude but opposite in direction.

Find the equation of a line that passes through the point (3,-2) and cuts off intecepts on the two axes which are equal in magnitude and opposite in sign.

Find the equations of the st. lines, which pass through the point (3, 4) and have intercepts on the axes : equal in magnitude but opposite in sign .

The coordinates of the point(s) on the graph of the function f(x)=(x^3)/x-(5x^2)/2+7x-4 , where the tangent drawn cuts off intercepts from the coordinate axes which are equal in magnitude but opposite in sign, are

Two long straight, current-carrying conductors , PQ and XY, are held a constant distance apart as shown in the figure. The conductors carry the magnitude of current in the same direction . A plan view form above the conductors is shown in the figure. Draw arrows, one in each case, to show the direction of the magnetic field at Q due to the current in wire XY. the force at Q as a result of the magnetic field due to the current in wire XY.

Two bodies of masses 10 kg and 20 kg respectively kept on a smooth, horizontal surface are tied to the ends of a light string, a horizontal force F = 600 N is applied to:-B along the direction of string. What is the tension in the string in each case?

Two bodies of masses 10kg and 20 kg respecively kept on a smooth, horizontal surface are tied to the ends of a lght string. A horizontal force F= 600 N is applied to (i) A (ii) B along the direction of string. What is the tension in the string in each case?

A copper and a steel wire of the same diameter are connected end to end. A deforming force F is applied to this composite wire which causes a total elongation of 1 cm. The two wies will have

Drift velocity in a metallic conductor: At room temperature there are large number of free electrons having zero average velocity, but when electric field is applied, the free electrons start moving in a direction opposite to the direction of the applied field with a velocity called drift velocity. The magnitude of electric field set up across the ends of the conductor is given by

Two equal charges placed in air separated by a distance 3 m repel each other with force 0.1 g f. Calculate the magnitude of either of the charges.
