Answer» The vector product of two vectors a and b is given by a vector whose magnitude is given by|a||b|sinθ(where0∘≤θ≤180∘), which stands for the angle between the two vectors. Note that the direction of the resultant vector is denoted by a unit vector^nwhose direction is perpendicular to both the vectorsaandbin a way thata, band^nare oriented in right-handed system. Right-handed orientation happens when vectorais twisted in the direction of vectorb, then the direction of the unit vector^ngoes in the direction in which a right-handed screw would spin if moved in a similar manner. Also, these given vectorsaandbcannot be called null vectors or non-parallel in nature. The right-hand thumb rule gives a clear picture of the direction of the resultant vector. |
