A wire is (7x - 3) metres long. A length of (3x - 4) metres is cut for use. Now, answer the following questions: If this left out wire is used for making an equilateral triangle. What is the length of each side of the triangle so formed?

A square field of area 31684 sq. metres is to be enclosed with wire placed at 1,2,3,4 metres above the ground. What length of the wire will be required, if the length required for each wire is 5% greater than the perimeter of the field?

Currents of 10A, 2A are passed through two parallel wires A and B respectively in opposite directions. If the wire A is infinitely long and the length of the wire B is 2 metre, the force on the conductor B , which is situated at 10cm distance from A will be
