.2 An apple falls from a tree
because of the gravitational
attraction between the earth
and the apple. If F1 is the
magnitude of the force exerted
by the earth on the apple and
F2 is the magnitude of the
force exerted by the apple on
the earth, then *
O
(a) F1 is very much greater than F2
(b) F2 is very much greater than F1
O (c) F1 and F2 are equal
O
(d) F1 is only a little greater than F2​

Answer 1

Answer:

The force of attraction f is equal to f₂ , option (d)

Explanation :

The gravitational force of attraction is given by

F = \frac{GMm}{r^2}r2GMm

Let the mass of the earth = M

mass of apple = m

distance between them = r

Force exerted by earth on the apple,

f = \frac{GMm}{r^2}r2GMm

similarly force exerted by apple on earth

f₂ = \frac{GMm}{r^2}r2GMm

so we can see that f is equal to f₂ , option (d)

Answer 2

Answer:

is option d...
