💡 Analysis & Explanation
Concept
200 N, because at constant velocity, the opposing friction force must exactly balance the applied force.
Condition
Constant velocity implies zero acceleration.
Force Balance
Net Force = Applied Force - Frictional Force = 0.
Result
Frictional Force = Applied Force = 200 N.
