The correct answer is 15 N.

Explanation:

The mechanical advantage of a machine is calculated as,

M.A = Output Force/ Input Force

Given, mechanical advantage=2

Output force = 30 N

Substituting the values,

2=\frac{30}{I.F}

Input force = 15 N

∴ The input force must be 15 N.

A suspended object A is attracted to a neutral wall. It's also attracted to a positively-charged object B. Which of the followin
olga2289 [7]

There are two particular cases, the first is when Object A is attracted to the neutral wall. This would indicate that the object is not neutral, as there is an attraction.

At the same time we know that Object A is attracted to an object B. And therefore, the load of A must be opposite to that of B. Remember that opposite charges attract each other. If the charge of object B is positive, then the charge of object A will be negative.

Option B is correct: It has a negative charge.
