Best ResponseYou've already chosen the best response.0the mass is 1 kg..... g=10m/s^2......so the external force acting on the spring is 10 newton

Best ResponseYou've already chosen the best response.010/(0.1*102) = 10*100*10=10000 N/m definitely......unofficial entry test book not issued by testing authority can have lots of errors....

Best ResponseYou've already chosen the best response.0f=mg=kx 0.1cm=.001m 1kg*10m/s^2=k*0.001m 10N/.001m=10000N/m

Best ResponseYou've already chosen the best response.0The above options are incorrect because. 1kg*10m^s2=! 1000N/m*.001m or 100N/m *.001m and etc
