Step 1: Understanding Center of Gravity.
The Center of Gravity (CoG) is the point at which the total mass of a body is considered to be concentrated. When a person holds an object in one hand, their CoG shifts towards the side of the body carrying the object, and it also moves downwards due to the additional weight.
Step 2: Analyzing the options.
- (1) Towards Left side and downwards: Incorrect, since the object is in the right hand, so the CoG shifts to the right.
- (2) Towards Left and upwards: Incorrect, as the CoG would not shift left or upwards in this case.
- (3) Towards Right and upwards: Incorrect, as the CoG moves downwards due to the additional weight.
- (4) Towards Right and downwards: Correct, since the person is carrying the suitcase with their right hand, the CoG shifts to the right and downward due to the added weight.
Step 3: Conclusion.
Thus, the correct answer is (4), as the CoG shifts towards the right and downwards.
