a) What is the acceleration due to gravity on
(i) Venus, (ii) Pluto, and (iii) the moon?

b) Three objects, carrying charges of –4.0 x 10–6 C, –6.0 x 10–6 C and +9.0 x 10–6 C, respectively, are placed in a line, equally spaced from left to right by a distance of 0.50 m. Calculate the magnitude and direction of the next force acting on each that results from the presence of the other two.

The surface pressure on Venus is 92.00 atmatm, and the acceleration due to gravity there is 0.894 gg. In a future exploratory mission, an upright cylindrical tank of benzene is sealed at the top but still pressurized at 92.00 atmatm just above the benzene. The tank has a diameter of 1.80 mm , and the benzene column is 11.10 mm tall. Ignore any effects due to the very high temperature on Venus. A) What total force is exerted on the...

2.) For this problem the heights are low enough that the acceleration due to gravity can be approximated as -g. (Note: even at low Earth orbit, such as the location of the International Space Station, the acceleration due to gravity is not much smaller then g. The apparent weightlessness is due to the space station and its occupants being in free-fall.) A rocket is launched vertically from a launchpad on the surface of the Earth. The net acceleration (provided by...

On a planet, the acceleration due to gravity is only 7.2 m/s2. A person living on that planet throws a football at 10 m/s at an angle of 48 degrees to the horizontal. The person is standing, so the ball launches from an initial height of 1.8 meters above the ground. (Ignore any air resistance here.) What maximum height from the ground would the ball reach? What would be the flight time before the ball gets back to the ground?

A rocket is fired from earth towards sun. Justify that acceleration due to gravity does not depend on mass of the rocket moving? Is the acceleration due to gravity on rocket at a point above earth, inversely related with square of distance of that point from earth? Explain shortly. Using the following data, how would you determine the point where the gravitational force on the rocket is zero? [ Note: neglect the attractive forces of other planets on the rocket]...
