What is the gravitational force between two objects, one with a mass 2.0×10^4 kg and the second with a mass of 3.0×10^4 kg, that are 1.5 M apart?(G=6.673
Answer: A. 1.77x10-² N
Explanation: Newton's Law of Universal gravitation is expressed in the following formula:
F= G x ( m1 x m2 ) / r²
= 6.673x10-¹¹ N.m²/kg² ( 2.0x10⁴ kg x 3.0x10⁴ kg) / (1.5m )²
= 0.0177 N or 1.77x10-² N
