An object whose mass is 4 kg experiences a gravitational force of 20 N at some point P. The gravitational field at this point is A) 5 m/s² B) 4 m/s² C) -5 m/s² D) 20 n/kg E) 80 N/kg

Question

Quizplus · Accepted Answer

The gravitational force experienced by an object is given by F = m*g, where m is the mass of the object and g is the gravitational field strength. So, we can calculate the gravitational field strength at point P as g = F/m = 20 N / 4 kg = 5 m/s^2.
Also, the direction of the gravitational field is always towards the center of the massive object causing the field, which in this case is not given. So, we assume that it is in the downward direction, which is the most common case. Therefore, the answer is (A) 5 m/s^2 downwards.
