    Direction Force
AI Thread Summary
The discussion focuses on determining the direction of force on a current-carrying wire in a magnetic field using Fleming's Left Hand Rule. The user successfully identifies the force direction for the first question, concluding it is "out." However, they express confusion regarding the current direction in the second question, noting it appears to flow diagonally down and to the right. Clarification on the current's direction is needed to apply the rule correctly for the second scenario. Understanding the correct application of Fleming's Left Hand Rule is crucial for solving these types of physics problems.

Homework Statement



[PLAIN]http://img695.imageshack.us/img695/5023/directionofforce.jpg
Basically I have to work out the force acting on a current-carrying wire in a magnetic field.

Homework Equations


Fleming's Left Hand Rule
(http://en.wikipedia.org/wiki/Fleming's_left_hand_rule_for_motors)

The Attempt at a Solution


Ok so for the first question (the one on the left)
index finger - pointing up
middle finger - pointing right

my thumb was pointing "out"
so the direction of the force acting on the wire was just "out"

For the second question
index finger - up
middle finger - ?

I'm totally stumped on what direction the current is flowing in :(

The current in the second picture appears to be flowing diagonally down and to the right.
 

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...
