NEET2009PhysicsMagnetic Properties of MatterActual
The magnetic force acting on a charged particle of charge -2 c in a magnetic field of 2 ~T acting in y direction, when the particle velocity is (2 i +3 j ) 10^6 ~ms ⁻¹ , is :
Options
- A8 ~N in z - direction
- B8 ~N in z - direction
- C4 ~N in z - direction
- D8 ~N in y - direction
Correct answer
B. 8 ~N in z - direction
Step-by-step solution
aligned F & = q ( v B ) & =-2 10⁻⁶ [(2 i +3 j ) 10^6 2 j ] & =-(8 ~N ) k aligned
