A single turn current loop in the shape of a right angle triangle with side 5 ~cm , 12 ~cm , 13 ~cm is carrying a current of 2 ~A . The loop is in a uniform magnetic field of magnitude 0.75 ~T whose direction is parallel to the current in the 13 ~cm side of the loop. The magnitude of the magnetic force on the 5 ~cm side will be x 130 ~N . The value of ' x ' is
Options
- A4
- B9
- C12
- D15
Correct answer
B. 9
Step-by-step solution
The net magnetic field is acting in the direction of GF as shown in figures: Resolving B into its components, amongst the components, only B exerts force on side EF of current carrying loop. F _ EF = I d ( EF ) B From figure ( a ), = 12 13 array ll & F _ EF =2 0.05 0.75 12 13 , & F _ EF = 9 130 ~N & x =9 array
