Answer:

C. 80N

Explanation:

Mechanical advantage

= Output force /input force

Given

M.A = 4

Input force = 20N

Output force = ?

Therefore

4 = output force /20

Cross multiply

Output force = 20 x 4

= 80N

Answer:80N

Explanation:

Mechanical advantage=4

Input force=20N

Output force=?

mechanical advantage(ma)=(output force) ➗ (input force)

4=(output force) ➗ 20

Output force=4 x 20

Output force=80N
