If radius of solid sphere is doubled by keeping its mass constant, thenA. `(I_(1))/(I_(2))=(1)/(4)`B. `(I_(1))/(I_(2))=(4)/(1)`C. `(I_(1))/(I_(2))=(3)/(2)`D. `(I_(1))/(I_(2))=(2)/(3)` |
Answer» Correct Answer - A `(I_(2))/(I_(1))=((2)/(5)MR_(2)^(2))/((2)/(5)MR_(1)^(2))=((R_(2))/(R_(1)))^(2)=(4)/(1)` `therefore (I_(1))/(I_(2))=(1)/(4)`. |
