Sorry about last time sorry the question is
If the masses of objects increase and their distance from each other remains the same, then the force of gravity between the two objects

A)
decreases.

B)
increases.

C)
remains the same.

D)
increases then decreases.

The particle p starts from rest at point a at time t = 0 and changes its speed thereafter at a constant rate of 2.8g as it follows the horizontal path shown. determine the magnitude and direction of its total acceleration (a) just before point b, (b) just after point b, and (c) as it passes point c. state your directions relative to the x-axis shown (ccw positive) and choose the angle with the smallest magnitude.
