Answer 1

Answer:

57×103 ms−1.

hope you are doing well

Answer 2

Explanation:

Speed, v=49.57×10

3

ms

−1

.

Explanation:

We have,

De Broglie wavelength of a proton is,

λ=0.08A

0

=0.08×10

−10

m

It is required to find the speed of the proton.

The De-Broglie wavelegth in terms of speed of proton is given by:

λ=

mv

h

v=
