Answer : Statement-1 is true,Statement-2 is true and Statement-2 is the correct explanation for statement-1
If the acceleration vector is not directed towards the centre of the circle,it will have a component along the tangent,as a result the speed of the body will change and the motion no longer remains uniform.
