You can calculate this, using Newtons Equation of gravitation:
F = Gm1m2/r^2
where
F = force (N)
G = universal gravitational constant = 6.67 x 10^-11 (Nm^2kg^-2)
m1 = mass of Earth = 6 x 10^24 kg
m2 = mass of Sun = 2 x 10^30 kg
r = distance from earth to sun = 1.5 x 10^11 m

Gravitational attraction is expressed wth the formula
f = G·m1·m2/r^2
That is, the gravitational force from object 1 to object 2 is G, the constant of universal gravitation, times the masses, divided by the square of the distance between them.
The gravitational force from object 2 to object 1 is the exact same amount, in the opposite direction.
The value of G is listed on the page linked below.

Hi. The Earth travels 90 degrees in 3 months. It would therefore take three months for the Earth to fall to the sun.

F= GMm/ r^2
M= mass of sun
m= mass of earth
r = distance between two mass center to center
