Auniform metal bar is 5.00 m long and has mass 0.300 kg. the bar is pivoted on a narrow support that is 2.00 m from the left-hand end of the bar. what distance x from the left-hand end of the bar should an object with mass 0.100 kg be suspended so the bar is balanced in a horizontal position

0.5 m

Explanation:

Given

length of Metal Bar L=5 m

mass of bar

mass of another object

Let this mass be hanged at a distance of y from Pivot so it cancel out the torque of weight of bar

Torque of weight of bar

torque by mass

Equating both torques

y=1.5 from Pivot point so it is 0.5 m form left end

explanation:

the atomic radius of a chemical element is a measure of the size of its atoms, usually the mean or typical distance from the center of the nucleus to the boundary of the surrounding shells of electrons.
