We've to find it inadequately weight thing at the admitted election if we know it carries the kinetic energy. Now we've to figure out the relationship between the very post in order to set up our equation. So we know we are looking for the weight length and we've been handed with the kinetic energy.
Now we know that Connect energy has a relationship with the haste. If we are going to rearrange the question then we've two times kinetic energy equals to mass haste forecourt or haste forecourt. You close to two times collected energy that bothered by the mass were haste because the square root of two times connected energy over the mass Right then. Now we've a relationship. They'd kinetic energy on the haste as well.
And now we just have to associate a haste with the wavelength can do this. It's close to cranks constant divided by the instigation we know Constant has a number of 6.63 times 10 to the power of native 34. rather of jewels per second, we are going to use kilograms either square per second, because on the weight of the electron then, which is9.1 times 10 to the power negative 31 we also have a kilogram. So we've to have a kilogram over there to cancel it now onto the haste. It's going to be a big bone , no, two times the kinetic energy, which is five or six. So we've to do a conversion of ev to 1.602 times 10 to the power of negative 19 augar developed by the mass again, which is9.1 times 10 to the power of -0.545 is the final answer.
