B.) 100 N is the CORRECT answer


Please mark as brainliest! :)

MA = Mechanical advantage of car jack = 6

\(F_{o}\) = Output force required to raise the car = 600 N

\(F_{i}\) = Input force required to raise the car = ?

Mechanical advantage is given as

MA = \(F_{o}\) /\(F_{i}\)

inserting the values

6 = 600/\(F_{i}\)

\(F_{i}\) = 600/6

\(F_{i}\) = 100 N

Hence the input force required comes out to be 100 N
