Objects with masses of 210 kg and a 510 kg are separated by 0.320 m. (a) Find the net gravitational force exerted by these objects on a 68.0 kg object placed midway between them. magnitude direction Select- (b) At what position (other than infinitely remote ones) can the 68.0 kg object be placed so as to experience a net force of zero? m from the 510 kg mass

2-D star cluster puzzle Find the net gravitational force on each star for each star cluster Let m=mass of the star = 1.99 x 10^30 kg, l=earth to star distance=149.6 x 10^6 km, G=6.67 x10^-11 N m^2/kg^2. Note that the masses of each star are the same. Also, it is advised to use vectors and components. And you can just find the gravitational net force of one of the stars in the shape 1) Triangle 2) Square 3) Pentagon 4) Hexagon 5) Regular heptagon 6) Regular Octagon

A 230-kg object and a 530-kg object are separated by 3.90 m. (a) Find the magnitude of the net gravitational force exerted by these objects on a 65.0-kg object placed midway between them. N (b) At what position (other than an infinitely remote one) can the 65.0-kg object be placed so as to experience a net force of zero from the other two objects? m from the 530 kg mass toward the 230 kg mass

Astrology, that unlikely and vague pseudoscience, makes much of the position of the planets at the moment of birth. The only known force a planet exerts on earth is gravitational. (a) Calculate the gravitational force exerted on a 5.00 kg baby by a 130 kg father 0.150 m away at birth (assisting so he is close). ______N(b) Calculate the force on the baby due to Jupiter if it is at its closest to the earth, some 6.29 ✕ 1011 m away, showing it to be comparable to that of the father. The mass of Jupiter is about 1.90 ✕ 1027 kg. Other objects in the room and the hospital building also exert similar gravitational forces. (Of course, there could be an unknown force acting, but scientists first need to be convinced that there is even an effect, much less that an unknown force causes it.)_____ N
