Could u help me with detailed solution.

It'll be very much helpful if you could provide the solution to this problem.

See lessMy ans: 100 Driving force for sintering is inversely proportional to the surface area [∆G proportional to 1/(R^2)]. (∆G1)÷(∆G2)=(R2÷R1)^2 ∆G2=100∆G1 Corrections are welcomed and thanked.

Driving force for sintering is inversely proportional to the surface area [∆G proportional to 1/(R^2)]. (∆G1)÷(∆G2)=(R2÷R1)^2

∆G2=100∆G1
