The earth is 8 light minutes from the sun and the
speed of light is 3x10 to the power of 8 m/s. Lets assume that the
earths orbit is exactly circular. It's mass is 5.972x10 to the
power of 24kg.
Using the values given above, determine the magnitude of the
gravitational force that the sun exerts on the earth
Homework Answers
distance between earth and sun
r = 8 * 60* 3* 10^8 = 1.44* 10^11 m
force
F = GMm / r^2 = 6.67* 10^-11* 5.98* 10^24* 5.972* 10^24 / (1.44* 10^11)^2
F = 1.154* 10^21 N

8. A cosmic-ray proton traveling at half the speed of light (speed of light c 3x10 m/sec) is heading directly towards the center of the Earth in the plane of the Earth's equator. Assume that the Earth's magnetic field is uniform over the planet's equatorial plan with a magnitude of IBI-50.0x10-6 T, extending out a distance d 1.3x107m from the surface of the Earth. Assume that the field is zero at greater distances. Will the cosmic-ray proton hit the Earth?...

An object of mass m moves at a constant speed v in a circular path of radius r.
An object of mass m moves at a constant speed v in a circular path of radius r. The force required to produce the centripetal component of acceleration is called the centripetal force and is given by F=mv2/r. Newton's Law of Universal Gravitation is given by F=GMm/d2, where d is the distance between the centers of the two bodies of masses M and m, and G is a gravitational constant. The speed required for circular motion is v= √(GM/r). Use the...
