Question

Solve this question .
2.4 is the right answer .

Answer 1

Answer:

Magnetic Field

Explanation:

# FORCE ON A MOVING CHARGE IN MAGNETIC FIELD #

Force ( F ) = Charge ( q ) × Velocity ( v ) × Magnetic Field ( B ) Sin ∅

★ Given ;

» Charge ( q ) = proton

» Velocity ( v ) = 2 × 10⁷ m / s

» Magnetic Field ( B ) = 5 wb / m²

★ Force = ??

_______________________________________________________________________________

F = 1.6 × 10-¹⁹ × 2 × 10⁷ × 5 × sin 30°

= 16 × 10-¹² × 1 / 2

Force = 8 × 10-¹²
