The force per unit length on a straight wire carrying current of 8 A making an angle of $30^{\circ}$ with a uniform magnetic field of 0.15 T is

• A

  $1.2 \mathrm{~N} \mathrm{~m}^{-1}$
• B

  $1.02 \mathrm{~N} \mathrm{~m}^{-1}$
• Correct answer
  C

  $0.6 \mathrm{~N} \mathrm{~m}^{-1}$
• D

  $2.4 \mathrm{~N} \mathrm{~m}^{-1}$

Hence, the correct answer is option: 'C'.
