9.3** (a) Consider the tidal force (9.12) on a mass m at the position P of Figure 9.4. Write d as(d。 — Re) = d(1 - Re/do) and use the binomial approximation (1 − e)-2 ≈1+2Є to show that≈ −(2GM…mRe/do³) ŷ. Confirm the direction of the force shown in Figure 9.4 and make anumerical comparison of the tidal force with the gravitational force mg of the earth. (b) Do thecorresponding calculations for the force at the point R. Compare this force with that of part (a)(magnitude and direction).Frid-

At a particular instant, in a coordinate frame chosen by us, the Earth (mass = 6 x 1024 kg) is at location (-7.30 × 106, -7.80 × 106, 3.73 × 106) m and the Moon (mass = 7 x 10²² kg) is at location (-1.35 × 108, -2.50 × 10³, 2.82 × 108) m. A satellite with mass 5000 kg is at location (-1.18 × 10³, -2.73 × 10³, 3.10 × 108) m. What is the net force on the satellite?

Black holes are difficult to observewith telescopes because they, bydefinition, don’t emit or reflect any light. They can be found by look-ing for other nearby objects orbit-ing them, however. Here is a dia-gram of a star in a circular orbit around a black hole. a. The period of the star’s orbit is 90 days, and its orbital radius around the black hole isobserved to be 3.6 : ×10^11 m. Find the orbital velocity of the star in units of m/s. (You need to convert 90 days to seconds, first). The circumference of a circle is 2πr. b. The mass of the star is known to be 4 × 10^30 kg. Find the centripetal acceleration of thestar and the strength of the gravitational force on the star. c. Find the mass of the black hole.
