Vector Question no. 16 If a , b and c are three coplanar vector , then looks_one a .( b ✕ c )=1 looks_two a .( b ✕ c )= 3 looks_3 c .( a ✕ b )=0 looks_4 b .( c ✕ a )=1 Answer Option looks_3 c .( a ✕ b )=0 Solution Solution : If a , b and c are three coplanar vector c .( a ✕ b )=0 Question no. 17 Given a = i + j - k and b= - i + 2 j + k , c= - i + 2 j - k . A unit vector prependicular to both a + b and c + b looks_one i looks_two j looks_3 k looks_4 ( i + j + k )/√3 Answer Option looks_3 k Solution Solution : a = i + j - k b= - i + 2 j + k c= - i + 2 j - k a + b = 3 j c + b = -2 i + 4 j A unit vector prependicular to both a + b and c + b is cross product of both vector.
