As we know that the formula of kinetic energy will be
now here we know that
m = 2 kg
v = 1 m/s
so from the above equation we have
Answer:
Explanation:
The change in potential energy can be expressed as:
where K is a constant with a value of , q1 and q2 are the charges of the proton and the electron and r is the distance between them.
The charge for the proton is and the charge for the electron is
.
Converting r=1.0nm to m:
Replacing values:
