PLSSS ANSWER WITHIN 15MINS
In the illustration below, suppose a moving rod is 0.11 m long, the velocity v is 216 cm/s, the total resistance of the loop is 0.014 Ω, and the magnetic field is 9325 G. Find the force acting on the rod.
Round your answer into the nearest 2 decimal place.
Final answer should be in two (2) decimal places.
For the final answer, express the unit in symbols. For example:
5.00 Kelvin should be expressed as 5.00 K
