Solution

The correct option is D
$0 k g$

Step 1. Given data
Mass of the body, $m = 1.0 k g$
Acceleration of body, $a = 10 m s^{- 2}$
Acceleration due to gravity, $g = 10 m s^{- 2}$
Step 2. Finding the apparent weight, $W$
By applying the formula of apparent weight,
$W = m (g - a)$
$W = 1 \times (10 - 10)$
$W = 0 k g$
Hence, the correct option is $(D)$ .
