1. Two identical, isolated particles, each of mass 2 kg, are separated by a
distance of 30 cm. What is the magnitude of the gravitational force of one
particle on the other?
2. A 200-kg mass and a 500-kg mass are separated by a distance of 0.40 m. (a)
Find the net gravitational force due to these masses acting on a 50-kg mass
placed midway between them. (b) At what position (other than infinitely
remote ones) would the 50-kg mass experience a net force of zero?
3. Three 5-kg masses are located at the corners of an equilateral triangle
having sides 0.25 m in length. Determine the magnitude and direction of the
resultant gravitational force on one of the masses due to the other two
masses.
4. Four particles are located at the corners of a
rectangle as in the Figure. Determine the x and y
components of the resultant force acting on the
particle of mass m.
