Answer: work = 8.34 Nm
Hi! The work W done by a force F to move an object from a to b is defined as (in the one dimensional case):
In this case
Answer:
The magnetic field reverses direction.
Explanation:
Given , F = 30N and mass m = 90kg
°•° F = ma
=> a = F/m
=> a = 30/90
=> a = 1/3m/s^2
Hypothesis after observation.
