Answer 1

Explanation:

Explanation:

The counterclockwise and clockwise torques about the pivot point must be equal for the rod to balance. Taking the fulcrum as the pivot point, the counterclockwise torque is due to the rod’s weight, gravitational force acting downwards at the center of the rod. If we use the pivot as our reference, then the center of the rod is 15cm from the reference.

τccw=r∗F=(0.15m)(10ms2)(0.2kg)=0.3N∗m

Set this equal to the clockwise torque due to the additional mass, a distance r to the right of the pivot.

τcw=r∗F=r(10ms2)(0.6kg)=0.3N∗m.

Solving for r gives r = 0.05m to the right of the pivot, so 40 + 5 cm from the left end of the rod.

hope it helps if not then sorryyyyyyyyy
