The points with position vectors `60 i+3j ,40 i-8j ,a i-52 j` are collinear if a. `a=-40` b. `a=40` c. `a=20` d. none of these

The points with position vectors 60hati+3hatj,40hati-8hatj, 40hati-8hatj,ahati-52hatj are collinear iff (A) a=-40 (B) a=40 (C) a=20 (D) none of these

If the points with position vectors 60hati+3hatj, 40 hati-8hatj and a hati - 52 hatj are collinear, then a =

The points with respective position vectors 60hat i+3hat j,40hat i-8hat j,xhat i52hat j are collinear if x is equal to

If the points with position vectors 60hat i+2hat j,40hat i-8hat j and adot i-52hat j are collinear,find the value of a .

IF the points with positon vectors 60hati+3hatj, 40hati-hata8j, ahati-52hatj are colinear, then prove that a=-40
