Question

Find tb−tt , the difference between the magnitude of the tension in the string at the bottom relative to that at the top of the circle.

Answer 1

Tension involves stretching or straining an object

The difference between the magnitude of the tension in the string is 25N

How to determine the tension difference

The tension acting on an object is calculated as:

$T = W\pm ma$

Where:

• W represents the weight of the object
• m represents the mass of the object
• a represents the acceleration of the object

The question is incomplete, so we make use of assumed values.

Assume that the magnitude of tensions acting at the top and the bottom of the string are:

tt = 25N

tb = 50N

Then, the difference in the magnitudes would be:

T =tb - tt

T = 50N - 25N

T = 25N

Using the assumed values, the difference between the magnitude of the tension in the string is 25N
