1.	The stress in a wire of diameter 2 mm, if a load of 100 g is applied to a wire, isA. `3.1xx10^(5)N//m^(2)`B. `6.2xx10^(5)N//m^(2)`C. `1.5xx10^(5)N//m^(2)`D. `12.4xx10^(5)N//m^(2)`
Answer» Correct Answer - A Stress `=(F)/(A) =(mg)/(pi r^(2))=(100 xx 10^(-3) xx 10)/(3.14 xx 10^(-6))` `=(1)/(3.14) xx 10^(6) =3.1 xx 10^(5)`
