Most Important Selected Qs for JEE AdvancedPhysicsMagnetic Properties of Matter
A jet plane is travelling west at 450 ~m / s . If the horizontal component of earth's magnetic field is 4 10⁻⁴ ~T and angle of dip is 30^ , then the vertical component is
Options
- A3 10⁻⁴ ~T
- B4 10⁻⁴ ~T
- C2.3 10⁻⁴ ~T
- D12.308 10⁻⁴ ~T
Correct answer
C. 2.3 10⁻⁴ ~T
Step-by-step solution
Given, B_ H =4 10⁻⁴ ~T Angle of dip , =30^ We know that, aligned &= B_ V B_ H B_ V &=B_ H &=4 10⁻⁴ 30^ &= 4 3 10⁻⁴ &=2.3 10⁻⁴ ~T aligned
