Explanation:
Whether explicitly stated or not, the value of the acceleration in the kinematic equations is -9.8 m/s/s for any freely falling object. If an object is merely dropped (as opposed to being thrown) from an elevated height, then the initial velocity of the object is 0 m/s.

Answer:
Q=4C
∆V=120V-100V=20V
W=Q X ∆V
4CX 20V=80J
Answer is 80J
Hope it helps
