Question

a block of mass 1 kg is suspended by a string of mass 1 kg length one metre. Calculate tansion in string at its lowest point

Answer 1

If we measure the tension of string at the lowest point.

Tension of sring(T) = mass pf the block.

Tension = mg

= l0N

Answer 2

Given :

Mass of block , m = 1 kg .

Mass of string , M = 1 kg .

To Find :

The tension in string at its lowest point .

Solution :

We know , tension at the lowest point of the string is only due to block .

Since , no other weight is applied in the block .

So ,

$T=mg\\\\T=1\times 9.8\ N\\\\T=9.8\ N$

Therefore , The tension in string at its lowest point is 9.8 N .
