In different experimental trials, an electron, a proton, or adoublycharged oxygen atom (O - -) is fired within avacuumtube. The particle's trajectory carries it through a pointwhere theelectric potential is 40 V and then through a point at adifferentpotential. Rank each of the following cases according tothe changein kinetic energy of the particle over this part of itsflight, fromthe largest increase to the largest decrease inkineticenergy.
Use only '>' or '=' symbols. If any elements are equal,showtheir equality in alphabetic order - for example: a>b=c.
(a) | an electron moves from 40 V to 60 V |
(b) | an electron moves from 40 V to 20 V |
(c) | a proton moves from 40 V to 20 V |
(d) | a proton moves from 40 V to 10 V |
(e) | an O- - ion moves from 40 V to 50 V |
(f) | an O- - ion moves from 40 V to 60 V |
For comparison, include also in your ranking: (g) | zero change |
(h) | +10 electron volts of change in kinetic energy |
