    because the arrow of F is toward left

    eduncle-logo-app

    yes for F the torque is upward or direction you did anti clockwise is correct but I am saying for tension torque as for this also anti clockwise only coming by curling of finger you pls look into it

    eduncle-logo-app

    no for F it is anti clockwise and for tension it is clockwise

    eduncle-logo-app

    for tension how clockwise you pls show me by diagram of T×r I am confused

    eduncle-logo-app

    when u have to calculate torque due to tension u have to hold the end of string and rotate toward the centre of circle it gives the direction of torque

    eduncle-logo-app

    see upward torque only coming as tension is greater so by curling towards it coming upward you see

    eduncle-logo-app

    no your way is wrong to find torque due to tension

    eduncle-logo-app

    the way I told is correct way to calculate tension torque

    eduncle-logo-app

    can you pls show the diagram

    eduncle-logo-app

    I told the way above please study even if u have problem then I will illustrate by some example

    eduncle-logo-app

    I did but still I am not able to get how the direction of torque coming for tension force as the tension is upward dirn if it would have been in downward direction then torque would have been clockwise but for upward tension how clockwise I can't get sir...
