Question

A charged particle of unit mass and unit charge moves with velocity v=(8^i+6^j)ms1 in a magnetic field of B=2^kT. Choose the correct alternative(s).
  1. the path of the particle may be x2+y24x21=0
  2. the time period of the particle will be 3.14s
  3. the path of the particle may be x2+y2=25
  4. the path of the particle may be y2+z2=25

A
the path of the particle may be x2+y2=25
B
the path of the particle may be x2+y24x21=0
C
the path of the particle may be y2+z2=25
D
the time period of the particle will be 3.14s
Solution
Verified by Toppr

v=8^i+6^j
B=2^k
m=1
q=1
r=mvqB=1×82+621×2=5
