Final answer:

The weight of a 10 kg apple on Earth is calculated using the formula w = mg, which gives us 98 N, making the correct answer c) 98 N.

Step-by-step explanation:

If an apple has a mass of 10 kg on Earth, to find its weight we can use the formula f = ma, where f is the force (weight) in newtons, m is the mass in kilograms, and a is the acceleration due to gravity in meters per second squared. On Earth, the acceleration due to gravity, g, is about 9.80 m/s². Therefore, the weight of the apple on Earth is calculated as:

w = mg = (10 kg)(9.80 m/s²) = 98 N.

Thus, the correct answer is c) 98 N.

Remember, when calculating the weight of an object, the acceleration due to gravity can take a positive or negative value, depending on your choice of coordinate system. However, the magnitude of the weight remains the same.
