Question

explain the attachment and answer it..​

Answer 1

Correct option is 4

We know that

g is directly proportional to 1/r square

[∵ mass is unchanged ]

Now, if the radius is halved then g will become 4 times

This means that the weight of the body will also become 4 times as weight is the product of mass and acceleration due to gravity.
