Not quite, you have to multiply distance by the force applied to the object (its weight in Newtons), but they’re using its mass (kilograms).
It’s actually 98 Nm, since weight = mass * gravitational acceleration and g ≈ 9.8 m/s² (you’ll see people give more digits but it actually varies by at most 0.1 m/s² or so depending on where you are).
