Physics Bookmark A charged particle is projected in a magnetic field B =(3 i +4 j )×10 −2 T and the acceleration is found to be a =(x i +2 j )m/s 2 . The value of x is : Medium Answer Correct option is A -8/3 m/s 2 F =q( V × B ) So F ⊥ B ∴ F ⋅ B =0 m a⋅ B =0 a ⋅ B =0 (x i +2 j )⋅(3 i +4 j )=0 3x+8=0 x= 3 −8
