Solution
The correct option is C 10J
Step 1: Given data:
The mass of the object = 1kg
The distance moved by the object = 1m
Gravitational acceleration g = 10 m/s²
Step 2: Work done is calculated using the formula,
W = F.S
Where F is the force
S is the displacement
The fore of the object is calculated from the formula,
Force, F = mg
m is the mass
g is the acceleration due to gravity.
Therefore,
W=1 kg ×10 m/s² ×1m
W= 10J
Therefore, the correct answer is C.
Final answer: The correct option is c)10 J
