Answer:

the gravitational field strength is 8.5 N/kg .

Explanation:

PE = mgh

where,

PE is Potential Energy

m is the mass

g (a) is the acceleration

h is the height

Substitute the value we get

→ 850 = 50×a × 2

→ 850 = 100×a

→ a = 850/100

→ a = 8.5m/s²

Acceleration is 8.5m/s².

Now, Calculating the Gravitational Field Strength
