A charge particle is moving in a uniform magnetic field (2i^+3j^)T. If it has an acceleration of (αi^−4j^)m/s2, then the value of α will be :

Multiple Choice Options

  • A 3
  • B 6
  • C 12
  • D 2

Step-by-Step Verified Solution

As magnetic force is perpendicular to magnetic field

So, F→ . B→ must be 0

So, 2α − 12 = 0

α = 6
