If vector F is 4i^ - 3j^ then its perpendicular vector is ?

1.	If vector F is 4i^ - 3j^ then its perpendicular vector is ?
Answer» Since. the given vector F = 4I^ - 3j^ Suppose the perpendicular vector is ai^ + bj^ actually actually vectors 4i^ - 3j^ and ai^ + bj^ are perpendicular to each other. . So, the ANGLE between both the vectors will be 90 o. So, (4i^ - 3j^) . (ai^ + bj^) = 0 or 4a - 3b = 0 or a/b = 3/4. So, the perpendicular vector will be (3I^ + 4j^)

Answer»

Since. the given vector F = 4I^ - 3j^

Suppose the perpendicular vector is ai^ + bj^

actually actually vectors 4i^ - 3j^ and ai^ + bj^ are perpendicular to each other. . So, the ANGLE between both the vectors will be 90 o.

So, (4i^ - 3j^) . (ai^ + bj^) = 0

or 4a - 3b = 0

or a/b = 3/4.

So, the perpendicular vector will be (3I^ + 4j^)
