Question

A body weighing 0.5kg tied to a string is projected with a velocity of 10m/s the body starts whirling in a vertical circle if the radius of the circle is 0.8m find the tension in the string when the body is at the top of the circle (ans T=3.8 N)​

Answer 1

Answer:

A body weighing 0.5kg tied to a string is projected with a velocity of 10m/s the body starts whirling in a vertical circle if the radius of the circle is 0.8m find the tension in the string when the body is at the top of the circle (ans T=3.8 N)

Answer 2

Answer:

The tension in the string when the body is at the top of the circle is 38 N.

Explanation:

Step 1: In physics, tension is defined as the pulling force that is transmitted axially by a string, rope, chain, or other similar object, or by each end of a rod, truss member, or other comparable three-dimensional object. Tension can also be defined as the action-reaction pair of forces acting at each end of the aforementioned elements.

Step 2: Given:

$m=0.5 \mathrm{~kg}, \mathrm{u}=10 \mathrm{~m} / \mathrm{s}, \mathrm{r}=0.8 \mathrm{~m}$

To find: Tension at highest point $\left(T_H\right)$

Step 3: Formula: $T_H=\frac{m}{r}\left(u^2-5 r g\right)$

Calculation:

From formula,

$\begin{aligned}& \mathrm{T}_{\mathrm{H}}=\frac{0.5}{0.8}\left(10^2-5 \times 0.8 \times 9.8\right) \\& =\frac{0.5}{0.8}(100-39.2) \\& =\mathbf{3 8} \mathrm{N}\end{aligned}$
