Physics - NLM Question with Solution | TestHub

The object moves due north with increasing speed, so its acceleration is directed due north (velocity stays along north, only its magnitude grows).

By Newton's second law the NET force must be directed due north - (B) correct.

This net force could be supplied by a single force due north - (A) is possible, hence correct.

No individual force need be the largest or point north; only the vector sum must point north - (C) wrong.

We can conclude something about the forces (their sum points north) - (D) wrong.

Correct options: (A), (B).
