Problem

A uniform light rod

1.0\,\text{m}

long is hinged at one end. A

50\,\text{N}

force is to be applied at an angle of

60^{\circ}

to the rod so that the torque about the hinge is

35\,\text{N\,m}

. At what distance from the hinge should this force be applied? (a)

0.70\,\text{m}

(b)

1.00\,\text{m}

(c)

0.81\,\text{m}

(d)

0.60\,\text{m}
