Question:medium
The velocity and acceleration vectors of a particle undergoing circular motion are \( \vec{v} = 2i + 4j \, \text{m/s} \) and \( \vec{a} = 2i + 4j \, \text{m/s}^2 \) respectively at an instant of time. The radius of the circle is a
The velocity and acceleration vectors of a particle undergoing circular motion are \( \vec{v} = 2i + 4j \, \text{m/s} \) and \( \vec{a} = 2i + 4j \, \text{m/s}^2 \) respectively at an instant of time. The radius of the circle is a
Show Hint
In circular motion, the radius can be determined using the formula \( r = \frac{v^2}{a} \), where \( v \) is the speed and \( a \) is the acceleration.
