Explanation / Answer

kinetic energy=1/2mv2=1/2X(6.64X10-24)X(.02X3X108)2J calculating we will get the value.

1b) 1 electron volt=1.6X10-19J

so 1 J=1/(1.6X10-19) ev

using this conversion factor we will get the answer in in electron volt(ev)

c) (x) volt=X volt X   1.6X10-19= 1/2X(6.64X10-24)X(.02X3X108)2J

calculating we wil get the value X which stands for voltage
