If two bodies of masses 2000 kg and 4000 kg are separated by a distance of 10m the gravitational force attraction between them is a)6.67×10‐¹¹N b)48.85×10^7N
c)53.36N
d)53.36×10^‐7N

d)53.36×10⁻⁷N

Step-by-step explanation:

The formula for gravitational force between two bodies is given by

F = G (Mm/r²)

Where,

F = gravitational force ( we are asked to find this)

G = gravitational constant = 6.674 x 10⁻¹¹

M = mass of one of the bodies = 4000 kg

m = mass of the the other body = 2000 kg

r = distance between the two bodies = 10m

substituting the above values into the equation:

F = G (Mm/r²)

= (6.674 x 10⁻¹¹) (4000)(2000) / (10²)

= 5.339 x 10⁻⁶

= 53.39 x 10⁻⁷  Newtons

The closest answer to this is d

answer set (b) 0.5, 3/4 80% is in order from least to greatest.  

step-by-step explanation:

in order to compare rational numbers to each other, it is much easier if they are in the same form.   typically, the best form in which to evaluate rational numbers is in decimals.   in order to convert a percent to a decimal, you would divide the given percentage by 100.   you can also accomplish the conversion by moving the decimal point over two places to the left.   for example, the decimal value of 80% is 80/100, or 0.8.   in order to convert a fraction to a decimal, you need to divide the numerator by the denominator.   for example, 3/4 is 0.75.   so, for choice (b) 0.5 3/4 (0.75), 80% (0.8) is the only choice in which the numbers are in order from least to greatest.
