A rod when suspended in a magnetic field stays in east-west direction. Can we be sure that the field is in the east-west direction? Can it be in the north-south direction?

A uniform magnetic field of 1.5 T exists in a cylindrical region of radius10.0 cm, its direction parallel to the axis along east to west. A wire carrying current of 7.0 A in the north to south direction passes through this region. What is the magnitude and direction of the force on the wire if, (a) the wire intersects the axis, (b) the wire is turned from N-S to northeast-northwest direction, (c) the wire in the N-S direction is lowered from the axis by a distance of 6.0 cm?

A cyclist travels 5km in the east direction. Then he travels 12km in the south direction. What is the magnitude of displacement of the cyclist ?

In the Cartesian plane, a man starts at origin and walks a distance of 3 units of the north-east direction and reaches a point P. from P, he walks a distance of 4 units in the north-west direction to reach a point Q. construct the parallelogram OPQR with OP and PQ as adjacent sides. let M be the mid-point of PQ.
