SUMMARY

The discussion focuses on determining the equation of line l2, which is perpendicular to line l1, given specific points. Line l1 is defined by the points (-3,2,3) and (-8,10,6). To find the equation of line l2 that passes through the point (7,49,25), one must first derive the equation of line l1 and then apply the properties of perpendicular lines in three-dimensional space. The solution involves using vector equations and understanding the geometric relationship between the lines.

Homework Statement



Two coplanar lines l1 and l2 are perpendicular to each other, l1 passes through the points (-3,2,3) and (-8,10,6). Find the equation for l2 if it passes through the point (7,49,25)

Homework Equations





The Attempt at a Solution


determine the equation of l1 and use the dot or cross product?

What you have under "The attempt at a solution" is NOT an attempt at a solution! If you think you neeed to find the equation of the line l1, the find it! What is the equation of that line? What must the equation of any line through (7, 49, 25) look like?
 
The book claims the answer is that all the magnitudes are the same because "the gravitational force on the penguin is the same". I'm having trouble understanding this. I thought the buoyant force was equal to the weight of the fluid displaced. Weight depends on mass which depends on density. Therefore, due to the differing densities the buoyant force will be different in each case? Is this incorrect?
