Question

We start with procedure 1: a magnet of length L is dropped so the front end is at height H from the coil, and you get a graph with two peaks. Each qeustion changes the procedure, and we wish to compare the new graph to this one.

d) Next: the original experiment is repeated on the Moon, where g, the acceleration due to gravity, is about one-sixth of g on Earth. If the magnet is dropped from height H, how will the graph compare to the original graph?
both peaks will be nearly zero
peak 1 will be the same as before, peak 2 will be the same as before
peak 1 will be slightly less than before, peak 2 will be the same as before
both peaks will be slightly less than before
both peaks will be the same as before
peak 1 will be slightly less than before, peak 2 will be zero
both peaks will be more than before
peak 1 will be nearly zero, peak 2 will be moe than before
peak 1 will be the same as before, peak 2 will be moe than before
peak 1 will be the same as before, peak 2 will be slightly less than before
peak 1 will be nearly zero, peak 2 will be the same as before
peak 1 will be slightly less than before, peak 2 will be moe than before
peak 1 will be nearly zero, peak 2 will be slightly less than before

Explanation / Answer

   both peaks will be more than before

   The speed at which magnet falls through the coil depends upon the height, as per    vf2   =   vi2 + 2 * g * H    i.e. grater is H greater is speed and hence greater is change in flux, which results in higher peaks.
