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

Explanation:

It is given that, in analyzing distances by applying the physics of gravitational forces, an astronomer has obtained the expression as :

We need to evaluate the value of R using calculator.

..............(1)

On solving equation (1) we get the value of R as :

So, the calculated distance from above expression is . Hence, this is he required solution.
