A) 6, 6, 4
B) 4, 6, 4
C) 3, 3, 2
D) 2, 3, 2
Correct Answer: A
Solution :
Here, \[{{x}_{2}}-{{x}_{1}}=6\], \[{{y}_{2}}-{{y}_{1}}=6\], \[{{z}_{2}}-{{z}_{1}}=4\] and d.c's of \[x,\,y,\,z\]-axes are (1,0,0), (0,1,0), (0, 0, 1) respectively. Now projection = \[({{x}_{2}}-{{x}_{1}})l+({{y}_{2}}-{{y}_{1}})m+({{z}_{2}}-{{z}_{1}})n\] \[\therefore \] Projections of line AB on co-ordinate axes are 6, 6, 4 respectively.You need to login to perform this action.
