Which of the following statements is true?
a. The bodies interacting exerts equal gravitational force on each other.
b. The gravitational constant G varies depending on the medium.
c. The less massive object exerts more gravitational force than the massive
one.
d. The massive object exerts more gravitational force than the lesser one.
The weight of bodies may change somewhat from one location to another as a result of the variation of the gravitational acceleration g with elevation. Accounting for this variation using the relation g = a − bz where a = 9.807 m/s2 and b = 3.32 × 10−6 s−2, determine the weight of an 80-kg person at sea level (z = 0), in Denver (z = 1610 m), and on the top of Mount Everest (z = 8848 m).
A stone falling from the roof of a single story building to the surface of the earth (which one?):
a) reaches its maximum speed quite soon after release and then falls at a constant speed thereafter
b) falls because of the intrinsic tendency of all objects to fall toward the earth
c) speeds up because of the constant gravitational force acting on it
d) speeds up as it falls, primarily because the closer the stone gets to the earth, the stronger the gravitational attraction
e) falls because of a combination of the force of gravity and the air pressure pushing it downwards

Find the resultant gravitational force exerted by the other two objects on the object at the origin.arrow_forward
- In the law of universal gravitation, Newton assumed that the force was proportional to the product of the two masses (m1m2) . While all scientific conjectures must be experimentally verified, can you provided arguments as to why this must be? (You may wish to consider simple examples in which any other form would lead to contradictory results.)arrow_forwardThe starship Enterprise has its tractor beam locked onto some valuable debris and is trying to pull it toward the ship. A Klingon battle cruiser and a Romulan warbird are also trying to recover the item by pulling the debris with their tractor beams as shown in Figure P5.25. a. Given the following magnitudes of the tractor beam forces, find the net force experienced by the debris: FEnt = 7.59 106 N, FRom = 2.53 106 N, and FKling = 8.97 105 N. b. If the debris has a mass of 2549 kg, what is the net acceleration of the debris? FIGURE P5.25arrow_forwardtwo particles, of masses m and 2m, are fixed in place on an axis. (a) Where on the axis can a third particle of mass 3m be placed (other than at infinity) so that the net gravitational force on it from the first two particles is zero: to the left of the first two particles, to their right, between them but closer to the more massive particle, or between them but closer to the less massive particle? (b) Does the answer change if the third particle has, instead, a mass of 16m? (c) Is there a point off the axis (other than infinity) at which the net force on the third particle would be zero?arrow_forward
