Aproton moves through a region containing a uniform electric field given by e = 56.0 j v/m and a uniform magnetic field b = (0.200i + 0.300j + 0.400k ) t. determine the acceleration of the proton when it has a velocity v = 190i m/s.

Explanation:

given,

E = 56.0 j V/m

B = (0.2 i + 0.3 j + 0.4 k ) T

v = 190 i m/s

mass of proton = 1.67 x 10⁻²⁷ Kg

e = 1.6 x 10⁻¹⁹ C

acceleration of proton is equal to = ?

magnetic force

F_B = e v B

F_B = e x (190 i) x (0.2 i + 0.3 j + 0.4 k)

F_B = e x (57 k - 76 j)

for proton electric force
