SECTION 3 (Maximum Marks : 18)
• This section contains SIX questions of matching type
• The section contains TWO tables (each having 3 columns and 4 rows)
• Based on each table, there are THREE questions
• Each question has FOUR options
A charged particle (electron or proton) is introduced at the origin (x = 0, y = 0, z = 0) with a given initial velocity . A uniform electric field and magnetic field Bare given in columns 1, 2 and 3, respectively. The quantities E0, B0 are positive in magnitude. | ||
Column 1 | Column 2 | Column 3 |

(II) Electron with | (ii) | (Q) |
(III) Proton with | (iii) | (R) |
(IV) Proton with | (iv) | (S) |
Text Solution
Verified by ExpertsCHECK THE SOLUTION.
(i)
For constant velocity

(ii)
For helical path, having its axis along z-axis, B must be along z-axis.
(iii)
and
must be along same line (i.e. parallel or anti parallel) with initial velocity either zero or along the field (
as well
).
