A pair of bullocks exerts a force of 140 N on a plough. The field being ploughed is 15 m long. How much work is done in ploughing the length of the field? - Physics Cbse class 11 1 AnswerTwo long, straight parallel conductors carrying steady currents I1 and I2 are separated by a distance d. Explain how the magnetic field due to one conductor acts on the other. Hence, deduce the expression for the force acting between the two conductors. Also mention how the direction of the force is determined. (Physics CBSE 2018)0 Answerhow many yards is the perimeter of the field?
