Toy Airplane Flying: Lift Force vs. Reaction Force

AI Thread Summary
The discussion centers on the relationship between lift force and reaction force in the context of a toy airplane flying in a horizontal circle. It clarifies that the lift force is not the same as the reaction force; instead, it is equal to the weight force plus the vertical component of the tension in the cord. The centripetal force acting on the airplane is identified as the horizontal component of the tension force. This distinction is crucial for understanding the forces at play in circular motion. Overall, the dynamics of lift and centripetal forces are essential for analyzing the airplane's flight.

Hi I've got a question concerning a previous question I've done. A person is holding a toy airplane which flys in the air with a constant radius.

is the lift force the same as reaction force?

is it equal to the vertical component of the centripetal force and weight force of the airplane?

Assuming the plane is flying in a horizontal circle of constant radius, the lift force is equal to the weight force plus the vertical component of the tension force in the cord. The centripetal force is the horizontal component of the tension force.
 

Thread 'Rolling without slipping on a curved surface'

Kindly see the attached pdf. My attempt to solve it, is in it. I'm wondering if my solution is right. My idea is this: At any point of time, the ball may be assumed to be at an incline which is at an angle of θ(kindly see both the pics in the pdf file). The value of θ will continuously change and so will the value of friction. I'm not able to figure out, why my solution is wrong, if it is wrong .

Thread 'Struggling to understand the concept of this question (ice cube in water optics question)'

TL;DR Summary: I came across this question from a Sri Lankan A-level textbook. Question - An ice cube with a length of 10 cm is immersed in water at 0 °C. An observer observes the ice cube from the water, and it seems to be 7.75 cm long. If the refractive index of water is 4/3, find the height of the ice cube immersed in the water. I could not understand how the apparent height of the ice cube in the water depends on the height of the ice cube immersed in the water. Does anyone have an...
