Q81 / 270 · NDA 2016 (Phase 2) · General Ability
When a force of 1 newton acts on a mass of 1 kg which is able to move freely, the object moves in the direction of force with a/an
- Aspeed of $1 \mathrm{~km} / \mathrm{s}$
- Correct answerBacceleration of $1 \mathrm{~m} / \mathrm{s}^2$
- Cspeed of $1 \mathrm{~m} / \mathrm{s}$
- Dacceleration of $1 \mathrm{~km} / \mathrm{s}^2$
Solution
$\begin{aligned} & \text { Force }(\mathrm{F})=\text { Mass }(\mathrm{m}) \times \operatorname{acceleration}(\mathrm{a}) \\ & \text {acceleration } \begin{aligned}(\mathrm{a}) & =\text { Force }(\mathrm{F}) / \operatorname{Mass}(\mathrm{m}) \\ & =1 \text { newton } / 1 \mathrm{~kg}=1 \mathrm{~m} / \mathrm{s}^2\end{aligned}\end{aligned}$
Hence, the correct answer is option: 'B'.
