A wire placed along north-south direction carries a current of 10 A from south to north. Find the magnetic field due to a 1 cm piece of wire at a point 200cm north-east from the piece.

A particle undergoes three successive displacements given by s_(1) =sqrt(2) m north - east , s_(2)=2 m due south and s_(3) =4 m, 30^(@) north of west , then magnitude of net displacement is

An aeroplane has a velocity of 110 m/s directed due north and is subjected to a wind blowing from west to east at a speed of 40 m/s . Calculate the actual velocity of the aeroplane relative to the earth .

A uniform smooth rod (mass m and length l ) placed on a smooth horizontal floor is it by a particle (mass m ) moving on the floor, at a distance l/4 from one end elastically (e = 1) . The distance travelled by the centre of the rod after the collision when it has completed three revolutions will be

The horizontal component of the earth's magnetic field at a certain place is 3 xx 10^-5 T and the direction of the field is from the geographic south to the geographic north. A very long straight conductor is carrying a steady current of 1 A. What is the force per unit length on it when it is placed on a horizontal table and the direction of the current is (a) east to west, (b) south to north?
