The number of submissions remaining for each question part only changes if you submit or cha Assignmant Scoring You iast ??t,mission is used for your score Notes Ask Your Teac (o) Find the direction of shown below the force on a proton (a positively charged particle) moving through the magnetic fields in the figune the figure k) Field Force Direction (b) Repeat part (a), assuming the moving particle is an electron Field Force Direction At the equator, rear the surface of Earth, the magnetic field is approximately S2??uT northward, and the electric field is about 0 N/C downward in fair weather Find the gravitational, electric, and magnetic forces en an electron withi

Explanation / Answer

F = q (v x B)

q = +e for proton

F^ = v^ x B^

(A) v^ -> j

B^ -> -k

j x -k = -i

Ans: to the left

(B) v -> j

B-> i

v x B = j x i = - k

ans: into the page

(C) v-> -i , B -> -j , F -> k

Ans: Out of page

(D) v-> -i, B -> k => F -> j

Ans: upward  

(E) v^ -> i^ + j^

B^-> i^

v x B = -k^

Ans: into the page

(F) Ans: out of page

----------------------------

for electron q = -ve

so direction for each case will be reverse.

(A)to the right

(B) out of page

(C) into the page

(D) downward  

(E) out of page

(F) into the page
