Find a vector of magnitude 11 in the direction opposite to that of vec(PQ , where P and Q are the points (1,3,2) and (-1,0,8), respectively.

Find a vector of magnitude 11 in the direction opposite to that of 'vec PQ', where P and Q are the points (1,3,2) and (1,0,8) respectively.

If the position vectors of P and Q are hat i+3hat j-7hat k and 5hat i-2hat j+4hat k them the cosine of the angle between vec PQ and y-axis is (5)/(sqrt(162)) b.(4)/(sqrt(162)) c.-(5)/(sqrt(162)) d.(11)/(sqrt(162))
