A person says that he mesured the acceleration of a particle to be nonzero while no force was acting on the particle

The acceleration of a particle is found to be non zero while no force acts on the particle. This is possible if the measurement is made from

What is the effect on the acceleration of a particle if the net force on the particle is doubled?

What is the effect on the acceleration of a particle if the net force on the particle is doubled?

When a force F acts on a particle of mass m, the acceleration of particle becomes a. now if two forces of magnitude 3F and 4F acts on the particle simultaneously as shown in figure, then the acceleration of the particle is
