A
The 9 volt battery will create a magnetic field that is 6 times as strong as the 1.5 volt battery.
B
The 1.5 voli battery will produce a magnetic field that is 6 times as strong as the 9 volt battery
C
The 1.5 volt battery will produce a magnetic field that is 36 times as strong as the 9 volt battery
The two batteries will produce the same magnetic field strength

Photoelectrons with a maximum speed of 6.50 x 107 m/s are ejected from a surface in the presence of light with a frequency of 6.75 x 1014hz. if the mass of an electron is 9.10 x 10-31 kg, calculate in joules the maximum kinetic energy of a single electron. 3.84 x 10-15 j 1.92 x 10-15 j 5.92 x 10-23 j 3.07 x 10-16 j

During the experiment if you could triple the breakaway magnetic force with all other quantities left unchanged, what is the new value for the critical velocity if it was v0 (initial velocity), initially? (b) now if you halved the radius with all other quantities left unchanged, what is the new critical velocity if it was v0 (initial velocity), initially? (c) if during the experiment, critical velocity quadrupled with all other quantities left unchanged, what is the new breakaway force if its magnitude was initially f0,?
