What is the magnetic force of a 30m long power line that carries a current of 50A. The magnetic field runs perpendicular to the power line and has a strength of 30T.

A. 45000 T/N

B. 45 V

C. 45 N

D. 45000 N

Respuesta :

Answer:

F=BILsin90 when perpendicular sin90 =1 30T x50x30 so you can get 45000N
