Question #161a9 Physics Forces and Newton's Laws Defining Force 1 Answer Jane Feb 2, 2018 Young's modulus (#Y#) is expressed as #(F/A) /( (delta l)/l)# (where, #F# is the force, #A# is the cross sectional area #delta l# is change in length and #l# is the original length) Given, #Y=2*10^-11,A= 1/10000, (deltal)/l =1# So, #F=2*10^-15 N# Answer link Related questions Question #cf2dd What does force mean?
