Yes agree @Ganesh.

Approximately, it's 3200kg from formula.

P = π*Y*W^2*R4/4g.

w=2*N*Π/60=10.47 rad/sec.
r= 0.5m
g= 9.81 m/sec^2.

The answer is 3510.54 Kg.

Anyone please solve this.

p={π*(specific weight)*(rotational speed in rad/sec)^2*(radius)^2}/4*g.

But the specific weight given in the question is not correct it is given in kg/m^3(which is for density) and must be in kN/m^3.
