mechanics help, torque

A uniform rod AB of length 5m and mass 6kg is pivoted at C. where AC=1.5m . calculate the mass of the particle which must be attached at A to maintain equilibrium with the rid horizontal

can anyone tell me if my diagram is correct? because i keep getting the wrong answer!

thank you

I think that your diagram is not completely correct since the weight should be placed at the middle of AB and not on C

Okay, I have redrawn it,

so would me equation be

???

I would say yes !
