Answer:
Mechanical Advantage (MA)
Explanation:
The Mechanical Advantage (MA) of a machine is defined as:
where
is the output force
is the input force
Machines are used as force multiplier, which means that they are able to produce an output force which is greater than the input force (and example of machine is the lever). Therefore, the MA of a machine represents the "multiplication factor" of the input force: for instance, if a machine has a MA of 5, it means that the output force is 5 times the force applied in input.

Answer:
E = 1.19 N/C
Explanation:
Let's first determine the length of the arc which can be given as:
L= Rθ
where:
L = length of the arc
R = radius of curvature
θ = angle in radius
L = (9.09×10⁻²m)(2.59)
L = (0.0909)(2.59)
L = 0.235431 m
Then, the magnitude of electric field that Q produces at the center of curvature can be calculated by using the formula:
Since
where;
L = length
Q = charge
λ = density of the charge;
then substituting for λ, we have :
substituting our given parameter; we have:
E = 1.1889 N/C
E = 1.19 N/C
∴ the magnitude of the electric field that Q produces at the center of curvature = 1.19 N/C
