Option 1: Epidermis and Stele
The cortex is the region of the plant that is located between the epidermis (outer layer) and the stele (inner vascular region). The cortex mainly consists of parenchyma cells and plays a role in storage and transport of materials.
The other options are incorrect because:
The cortex is located between the epidermis and stele, which makes Option 1 the correct answer.
A bob of heavy mass \(m\) is suspended by a light string of length \(l\). The bob is given a horizontal velocity \(v_0\) as shown in figure. If the string gets slack at some point P making an angle \( \theta \) from the horizontal, the ratio of the speed \(v\) of the bob at point P to its initial speed \(v_0\) is :
