Answer:

0.75 N

Explanation:

F=ma

mass change to kg -> 25 g to 0.25 Kg

0.25x3 =0.75 N

An electron and a proton have the same kinetic energy upon entering a region of constant magnetic field and their velocity vecto
kupik [55]

Answer: rp/re= me/mp= 544 * 10^-6.

Explanation: To calculate this problem we have to consider the circular movement by the electron and proton inside a magnetic field.

Then the dynamic equation for the circular movement is given by:

Fcentripetal= m*ω^2.r

q*v*B=m*ω^2.r

we write this for each particle then we have the following:

q*v*B=me* ω^2*re

q*v*B=mp* ω^2*rp

rp/re=me/mp=9.1*10^-31/1.67*10^-27=544*10^-6

meriva

Answer:

4948020

Explanation:

(6.9*10-6)(770*102)

<u>Multiply  6.9  by  10 . </u>

( 69 − 6 ) ( 770 ⋅ 102 )

<u>Subtract  6  from  69 . </u>

63 ( 770 ⋅ 102 )

<u>Multiply  770  by 102 . </u>

63 ⋅ 78540
