D: An electromagnet with 20 coils.
That is because the more coils of the wire, the stronger the electromagnet is.
You must find the component of the force before calculating
Answer:
No ! its False
Explanation:

Answer:
Where can I get a can opener? hahaha
Answer:
the bending moment will be W from either sides
Explanation:
bending moment= force (load) * perpendicular distance, if I understand the question the distance will be 1/2 of the length
=> f x 1/2(l) =W*1/2(2) =W
