NEETPhysicsMagnetic Effects of Current
A charged particle is introduced at the origin x = 0 , y = 0 , z = 0 with a given initial velocity v → . A uniform electric field E → and a uniform magnetic field B → exist everywhere. The velocity v → , electric field E → and a uniform magnetic field B → are given in the columns below Column 1 Column 2 Column 3 1. Electron with v → = 2 E 0 B 0 x ^ (i) E → = E 0 z ^ (P) B → = - B 0 x ^ 2. Electron with v → = 2 E 0 B
Options
- A( 4 ) ( i i ) ( S )
- B( 3 ) ( i i ) ( P )
- C( 2 ) ( i i i ) ( Q )
- D( 3 ) ( i i ) ( R )
Correct answer
D. ( 3 ) ( i i ) ( R )
Step-by-step solution
For particle to move in -ve y-direction, either its velocity must be in –ve y-direction (if initial velocity ≠ 0) and force should be parallel to velocity or it must experience a net force in –ve y-direction only (if initial velocity = 0)
