Q: An object of mass $5\text{ kg}$ is accelerated uniformly from a velocity of $4\text{ m/s}$ to $12\text{ m/s}$ in $4\text{ s}$. What is the magnitude of the force applied on the object?

Correct Option: B ($10\text{ N}$) Step-by-step Solution: Given Data: Mass of the object ($m$) = $5\text{ kg}$ Initial velocity ($u$) = $4\text{ m/s}$ Final velocity ($v$) = $12\text{ m/s}$ Time taken ($t$) = $4\text{ s}$ Calculate Acceleration ($a$): Using the formula for acceleration: $$a = \frac{v
