Acar jack with a mechanical advantage of 6 needs to produce an output force of 600 n to raise a car. what input force is required? 6 n 100 n 600 n 3,600 n

Input force = 100N

Explanation:

Formula

Mechanical Advantage = output force / input force.

Givens

MA = 6

Output Force = 600 N

Input Force = ??

Solution

6 = 600 / x

Multiply both sides by x

6x = (600/x)*x

6x = 600                

The xs cancel. Now Divide by 6

6x/6 = 600/6

x = 100 N

electrical potential energy =0.072 j

explanation:

electrical potential energy is given by

u= q δv

q= charge=6 c

δv= potential difference and is given by

δv= e d

e= electric field

d= distance=5 mm=0.005 m

δv=2.4 (0.005)=0.012 v

now electric potential energy= u= q δv

u=6 (0.012)

u=0.072 j
