What Are The Two Forces That Hold The Earth In Its Orbit Around The Sun?
my frnd.. it is the gravitational force . it was governed by Newton is knows as newtons law of gravitation. F=GMm/r^2
where M =mass of sun
m=mass of earth
G=universal gravitational constant
r=distance between two bodies
we can easily calculate the force on earth due to sun by knowing the values. tThis force act the earth perpendicular to the velocity of earth .that is why velocity of earth does not change. And the force which act perpendicular to its velocity . it is called centripital force. it is responsible for the circular motion of body. hope u wil understand
