Problem 69

A system is devised to exert a constant force of 8 N onan 80-kg body of mass initially at rest. The forcepushes the mass horizontally on a frictionless table.How far does the body have to be pushed to increaseits mass-energy by 25%?

Step-by-Step Solution:
Step 1 of 3

Week 12 Thursday, November 10, 2016 10:59 AM  Mass spectrometer: r=mv/qB ○ Find mass to charge ratio ○ Isotopes- atoms w same number proton but diff mass  Moving q in resp to MF: f=qvbsin(theta)  Current resp to MF: F=IBLsin(theta)  Current loop resp to MF: uBsin(theta)  MF in long straight wire ○ RHR #2: helps find dir of MF  Hold wire in right hand  Thumb in dir of current  Curl fingers in dir of MF(B) ..when current rev, MF reverses ○ Features of MF:  Lines of MF form circles about wire  Lines of MF lie in plane perp to wire  Symmetry, so mag of Mfis same on circular path centered on wire ○ Mag of MF proportional to I  Inversely proportional to distance r from wire  U0(u nought)-permitivety of free space □ Constant: 4pi x 10^-7 Tm/A  Derive relationship btwn I in arb shaped wire and MF from wire: ○ Ampere's Circuital law: sum of all prod's of B and delta L over closed path =u0I, where I is current that passes thru surface bounded by the closed path  Choose arb closed path around I ○ Ex) det dir of MF Symm analysis…forgiven r, MF is constant Circumference of circle is 2pir B(2pir)=u0(I) So B=(u0I)/(2pir)  Ex)Coaxial cable- insulated wire carrying 3A, surrounded by conductor carrying 1A in opp dir ○ Find
