1.	3. If an object is moving on a curved path, then which of the following physical quantities may be constant during the motion? (Symbols have usual meanings) (1) dv (magnitude)/dt (2) v vector (3) a vector (4) Both (1) & (3)Answer is 4th option, Can someone explain me how Acceleration(vector) is constant?
Answer» option 1Explanation:when an object follows a curved path , TIS magnitude as linear velocity MEANS speed will not CHANGE but DIRECTION will change . HENCE for accerleration of an object change but its magnitude remains same
