A0.5-kg ball accelerated at 50 m/s2 . what force was applied?

The answer is Force is equal to 25N

Explanation:

1) Taking into account Newton's second law, which expresses that the acceleration that a body acquires is directly proportional to that resulting from the forces acting on it, and has the same direction as that resulting.

2) This law is expressed with the formula F = ma where (F) represents force, (m) represents mass and (a) represents acceleration.

3) knowing this we can replace the values given in the problem and solve:

F = (0,5kg)(50m/s^2)

F = 25N

the answer would most likely be c, because if it's a comical piece of information, it may likely not be true, if it's a site that allows anybody to edit the content, it could mean a five year old is typing the info, and if it's a tv show produced by a celeb, it may have a biased opinion.

electric field is a function of 1/r^2

yes, the force per unit charge for a point charge is inverse square law.
