Calculate the gravitation force of attraction between two planets of 10^24kg and 10^27kg separated by a distance of 10²°meters.

The resultant force of a couple is _____?

A. Infinity B. Zero C. One D. Half Correct Answer: Option B – Zero Explanation Note: moment of a couple = force × length (fL) The tangential force is actingin an opposite direction alongside its length i.e f1L1 = f2L2 f2L2 − f1L1 = 0 (i.e...
