1.youngs modulus of elasticity of a perfectly rigid body is

a.unity b.zero c.infinity d.none of these

2.bulk modulus of a perfectly rigid body is

a.unity b.zero c.infinite d.some finite small non-zero constant value

Hello,
 
The Young’s Modulus of elasticity and the Bulk Modulus of a perfectly rigid body is equal to infinity.
 
Good Luck!
