Question 5 of 75 in this shift, Physics question 5 of 25, Section A.

Consider two solid spheres of radii

R_1 = 1

R_2 = 2

m and masses

M_1

and

M_2

, respectively. The gravitational field due to sphere (1) and (2) are shown. The value of

\frac{M_1}{M_2}

is :

The figure, in words

Graph of gravitational field E (vertical, 1-4) vs radius R (horizontal, 0-5). Curve (1) rises linearly to peak E=2 at R=1 then decays; curve (2) rises linearly to peak E=3 at R=2 then decays.
