Question
Three point masses are attached by light inextensible strings of various lengths to a point O on the ceiling. All of the masses swing round in horizontal circles of various radii with the same angular frequency w (one such circle is drawn in the shown figure.) Then pick up the correct statement.
- The vertical depth of each mass below point of suspension from ceiling is different.
- The radius of horizontal circular path of each mass is same.
- All masses revolve in the same horizontal plane.
- All the particles must have same mass.
The correct answer is: All the particles must have same mass.
