Question

could someone help me with these 2 problems I'm can't get these 2 questions correct I'm struggling really bad could u please show your work and explain thank u so much!

Your best submission for each question part is used for your score My N At a certain location, the horizontal component of the earth's magnetic field is 4.8 x 105 T, due the proton north. A proton moves eastward with just the right speed, so the magnetic force on it balances its weight. Find the speed of mýs Show My Work tooan My -20 points An electron maves at a speed of 6.0 x 101 m/s perpendicular to a constant magnetic fi eld. The path is a circle of radius 1.0 x 10 m. (a) Find the magnitude of the electron's acceleration. m/? (b) what is the magnitude of the field? show My work Spar.??? O Tpeheeto search ?@?

Explanation / Answer

Fb = m g

and Fb = q v B sin(theta) and theta = 90 deg

Fb = q vB

q v B = m g

(1.6 x 10^-19) ( v) (4.8 x 10^-5) = (1.67x 10^-27) (9.8)

v = 2.13 x 10^-3 m/s .....Ans
------------------------------------------

(A) a_c = v^2 / r = (6 x 10^6)^2 / (1 x 10^-3)

{ value of radius is not clear, taking it to be 1 x 10^-3 m}

a_c = 3.6 x 10^16 m/s^2 .....Ans

(B) Fb = m a_c

q v B = m v^2 / r

B = m v / q r

B = (9.109 x 10^-31)(6 x 10^6) / (1.6 x 10^-19 x 1 x 10^-3)

B = 0.034 T
