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

If the points whose position vectors are 60i+3j, 40i-8j and li-52j are collinear then I =

If the points with position vectors 60hati+3j, 40hati-8hatj and ahati-52hatj are collinear, then a is equal to

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 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 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

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