NEET Physics (general) MCQ Question
Type: MCQ-conceptual-Medium-Class 11
Which of the following statements about the motion of a block connected to a trolley are correct?
A
The acceleration of the block and trolley system depends on the coefficient of kinetic friction.
B
The tension in the string remains constant regardless of the applied force.
C
The system will have a net force acting on it when the block is in motion.
D
The mass of the string can affect the tension in the system.
Correct Answer
Option A
Detailed Explanation
According to the NCERT context, the acceleration of the block and trolley system is influenced by the coefficient of kinetic friction, which directly affects the net force acting on the system. The tension in the string is not constant as it is affected by the forces acting on the block and trolley.
