Help please

A wire carries a current of 5.2 A from east to west through a 6.0 m section of wire in the earth's magnetic field of 1 × 10^-5 T at a location where the magnetic field points south. What is the magnitude of the magnetic force acting on the wire?

3.1 × 10^-4 N

3.1 N

5.2 × 10^-5 N

6.0 × 10^-5 N

nvm i got this one, i think

5.2*6.0*.0001

.000312=

3.1*10^-4 N

so is this A?
