Write unit vector in direction of N-E, N-W, S-W andS-E.

A car is moving with a speed of 10m s^(-1) , If the east direction taken as x-axis and the north direction as y-axis . Write the velocity vector of car in unit vector notation.If it is moving (a) in the direction of N-E,(b) in the direction of N-W ,(C ) in the direction of S-W , and (d) in the direction of S-E .

Write the law of reflection of a light beam from a mirror in vector from, using the directing unit vectors e and e' of the incident and reflected beams and the unit vector n of the outside normal to the mirror surrfcae.

38.If 'W' Joule is the work done in rotating the magnet from the field direction to a position that makes an angle 60^(@) with the direction of the field,the torque required to hold the magnet in that direction is 1) wN-m 2) (W)/(2)N-m 3) (W)/(sqrt(3))N-m, 4) sqrt(3)WN-m

If the incident ray on a surface is along the unit vector vec v ,the reflected ray is along the unit vector vec w and the normal is along the unit vector vec a outwards,express vec w in terms of vec a and vec v
