Question

PLEASE ANSWER ALL PARTS WITH APPROPRIATE FORMULAS (EXPLAIN FULLY)

1.) Two equal highly dense spherical masses M = 450 kg are positioned on the y axis (so x=0) at points given by y = -1.20 m and y = +1.20 m. A third small spherical mass m = 100 kg is located on the x axis at x = 0.880 m. Find the net gravitational force on the smaller mass m caused by the other two masses.

2.) The planet Alpha orbits the star Alminar at the distance ??=8.8×10^7 km in a circular orbit with period ??=1.70×10^7 s.The mass of planet Alpha is ??=3.4×10^24 kg.

(a) What is the acceleration of the planet Alpha?

(b) A second planet, Beta, orbits Alminar in a circular orbit at radius ??=1.42×10^8 km. What is the orbital period of planet Beta?
