Question

Protons passing without deflection through a magnetic field of 0.06 T are balanced by an electric field of 9000 V/m. What is
the speed of the moving protons?
0 1.5x 105 m/s
0 2.5x 10 m/s
o 1.5x 103 mis
0 25x105 m/s​

Answer 1

Answer:

Xmas and then you can get a new

Answer 2

Answer:

1.5×10^5 m/s

Explanation:

Eq = Bqv

v = E/B = 9000/0.06 = 150 × 10^3 m/s = 150 km/s

so v= 1.5×10^5 m/s
