(Eigure 1) Part B Express vector Fin the form of Fo,.F, wheee the x, y and z components are separated by commas VA Envd d0Explanation / Answer
Given,
B = 0.6 T i
v = 1.4 x 10^7 m/s
We know that magnetic force on a moving charge is given by:
F = q v B
a) v = -1.1 x 10^7 j
F = (-1.6 x 10^-19) [ (- 1.4 x 10^7 j ) x 0.6 i ]
F = (2.4 x 10^-12 j) x (0.6 i)
F = ( 0i , 0 j , -1.44 x 10^-12 k ) N
b) F = (-1.6 x 10^-19) [ 1.4 x 10^7 (- 0.707 j + 0.707 k ) x 0.51 i ]
F = [ (-1.92 x 10^-12 j + 1.92 x 10^-12 k ) x 0.6 j ]
F = (0 i -1.15 x 10^-12 , -1.15 x 10^-13 ) N
