"in analyzing distances by apply ing the physics of gravitational forces, an astronomer has obtained the expression
r= √1/([1/140×10^9 meter]^2 - [1/208×10^9]^2)
use your calculator to evaluate r. view available hint(s)
(a) 3.87 x 10-12 meter
(b) 1.72× 1011 meter
(c) 2.58 x 1011 meter
(d) 1.49 x 1011 meter "

The value of R is .

(B) is correct option.

Explanation:

Given that,

In analyzing distances by apply ing the physics of gravitational forces, an astronomer has obtained the expression

We need to calculate this for value of R

So, The nearest option of the value of R is

Hence, The value of R is .

the moon affects the earth gravitation ally, causing certain motions of that body and also producing tides in its ocean and atmosphere. the tidal wave in our atmosphere is, however, far too minute to be an effective cause in any known meteorological phenomenon.
