physics
when the metal sphere is suspended at the end of a meal wire its extension is 0.4mm. If another metal sphere of the same material with its radius half as the previous is suspended then extension would be ans: 1)0.05mm

physics
a metallic ring of radius 'r' and cross sectional area is fitted into an wooden circular disc of radius R (R greater than r).If he young's modulus of the material of the ring is Y, the fore with which the metal ring expands is : ans: 1.AY(R-r)/r
