Question

Chapter 13, Problem 025 Your answer is partially correct. Try again. A solid sphere of uniform density has a mass of 8.0 x 104 kg and a radius of 3.4 m. What is the magnitude of the gravitational force due to the sphere on a particle of mass 6.3 kg located at a distance of (a) 17 m and (b) 2.4 m from the center of the sphere? (c) Write a general expression for the magnitude of the gravitational force on the particle at a distancers 3.4 m from the center of the sphere. (a) NumberTo.0000001163211073 Units TN (b) Number 190.0000006979266436 (b) Number To 0000 110.0000006979266436 units in (c) |Fon m1 = k·r, where k = 1

Answer 1

17? M Sal": a) Here particle is outside of the sphere, hence F= 65 Lox F = 6.67 X15" x 8.0x60" x 6.3 tot6 32x107 N b) If point is insidle sphere then M° = /xg30 = 4 / 4 - or n = 2 x M Hence F - Ginom & Gx(7²) Mini is GMmv - 6.67 x16" x 8.0x109x6.3x264- 6597 X166 N. डापो C) F = 16 mm xy = 6.67x10" x 8.0Xlo x 63 x™ 718.553x107 Der N -- (3.4) Hence k=8.553x107 N/m Oy ob
