- #2Which of the sets given below may represent the magnitudes of three vectors adding to zero?
-(a) 2, 4, 8
(b) 4, 8, 16
(c) 1, 2, 1
(d) 0.5, 1, 2digAnsr: cAns : (c) 1, 2, 1
1,2 and 1 may represent the magnitudes of three vectors adding to zero.For example one of the vector of length 1 should make an angle of `` {135}^{\circ }`` with x axis and the other vector of length 1 makes an angle of `` {225}^{\circ }`` with x axis. The third vector of length 2 should lie along x axis.
