Expert Solution
Step 1

Given that the speed of the particle is constant and the acceleration is not zero. we know that any particle is accelerated only when act on the body and when the force acts on the body the either the direction of the velocity changes or the magnitude of the velocity changes. But, here it is given that he speed is constant, which indicate the magnitude of the velocity is constant. So, we can conclude that the direction the velocity is changing continuously but the speed remains constant, which is only possible in the uniform circular motion.
