Assertion (A) : If a^{\to},b^{\to} are two non collinear vectors then the vector component of b^{\to} along the line perpendicular to a^{\to} is {a^{\to}\times(b^{\to}\timesa^{\to})}/{|a^{\to}|}^2 Reason (R) : a^{\to}\times(b^{\to}\timesc^{\to}) = (a^{\to}.c^{\to})b^{\to} - (a^{\to}.b^{\to})c^{\to} and vector component of b^{\to} on c^{\to} is (b. c^{\to}/{|c^{\to}|})c^{\to}/{|c^{\to}|}

Correct Answer is : Both (A) and (R) are true and (R) is the correct explanation of (A)

Both (A) and (R) are true and (R) is the correct explanation of (A)

Both (A) and (R) are true but (R) is not the correct explanation of (A)
