A body, under the action of a force $F = 6 \hat{i} - 8 \hat{j} + 10 \hat{k}$ , acquires an acceleration of $1 m / s^{2}$ . The mass of this body must be :NEET 2009 (Mains)

Options:

Answer:

Solution:

$F ∣ F ∣ m = 6 \hat{i} - 8 \hat{j} + 10 \hat{k} = 6^{2} + 8^{2} + 1 0^{2} = 102 = \frac{∣ F ∣}{a} = \frac{10 2}{1} = 102 kg$
