  • #5
    A vector
    A→points vertically upward and
    B→points towards the north. The vector product
    A→×B→is
    -(a) along the west
    (b) along the east
    (c) zero
    (d) vertically downward.
    digAnsr:   a
    Ans : (a) along the west
    The vector product `` \stackrel{\to }{A}\times \stackrel{\to }{B}`` will point towards the west. We can determine this direction using the right hand thumb rule.
