Question1
An 8.00 point mass and a 15.0 point mass are held in place 50.0 apart. A particle of mass is released from a point between the two masses 19.0 from the 8.00 mass beside line connecting the two fixed masses.
Question2
Assume the Sun is mostly composed of hydrogen atoms. Suppose the mass of the Sun is 1.61 × 1030 kg, and the mass of a hydrogen atom is 1.672 × 10-27 kg.
How many atoms are there in the Sun?
