Q4) The tension Tin Newtons in the string of a yo-yo of mass O.001kgis. given by the function of two variables T(^,R) = 0.009 R 2r?+R? ris the radius of the spindal, is the radius of the youyo, where an d R and 9= 9.8 m /s?. Find the g = approximate change in Tif R increases From 4cm to 4*1cm and r increases from O•8 cm to O•9cm. use your answer t•exptainf the tension T increases or decreases
