(a) Find the net gravitational force exerted by these objects on a 49.0 kg object placed midway between them. magnitude direction --Select--- N (b) At what position (other than infinitely remote ones) can the 49.0 kg object be placed so as to experience a net force of zero? m from the 550 kg mass

In the figure, a rectangular slab of slate rests on a bedrock surface inclined at angle 0 = 27.8°. The slab has length L = 41.2 m, thickness T = 7.51 m, and width W = 14.1 m, and 1.0 cm³ of it has a mass of 3.2 g. The coefficient of static friction between slab and bedrock is 0.315. (a) Calculate the component of the gravitational force on the slab parallel to the bedrock surface. (b) Calculate the magnitude of the static frictional force on the slab. By comparing (a) and (b), you can see that the slab is in danger of sliding. This is prevented only by chance protrusions of bedrock. (c) To stabilize the slab, bolts are to be driven perpendicular to the bedrock surface (two bolts are shown). If each bolt has a cross-sectional area of 7.06 cm² and will snap under a shearing stress of 3.06 × 108 N/m², what is the minimum number of bolts needed? Assume that the bolts do not affect the normal force. (a) Number i (b) Number (c) Number i Units Units Units <

True of False: These masses are placed one above the other. They are not touching and they are exerting gravitational forces one each other. Because these two masses are placed one above the other, rather than side by side, the magnitude of the gravitational forces these masses exert on each other should not be expected to be equal.

A raindrop has a mass of 8.0 x 107 kg and is falling near the surface of the earth. Calculate the magnitude of the gravitational force exerted (a) on the raindrop by the earth and (b) on the earth by the raindrop. (a) Fraindrop (b) Fearth N N

G = 6.67 ×10−11 m3/kg/s2.When Jupiter is on the same side of the Sun as the Earth the distance between the Earth and Jupiter can be as small as 6.30 × 1011 meters. Knowing this, what is the max- imum force of gravity due to Jupiter on a 52.0 kg ASTR 110 student standing on the equator during Spring Break. DATA: Mass of Jupiter = 1.90 × 1027 kg

Two objects attract each other with a gravitational force of magnitude 1.02  10-8 N when separated by 19.8 cm. If the total mass of the two objects is 5.06 kg, what is the mass of each?

Eight particles, each of mass m, are situated at the corners of a cube of side a. Find the gravitational force exerted on any one of the particles by the other seven. Deduce the total gravitational force exerted on the four particles lying on one face of the cube by the four particles lying on the opposite face.
