Hello, here we have to analyze the statements.
00:03
This first statement suggests that our apparent weight is less than mg when we are moving in an elevator which is downwards.
00:13
So here, elevator is downwards.
00:16
Our gravity is acting down and the apparent weight is up.
00:27
Acceleration is downwards, so therefore this apparent weight is our mass times g minus accelerators.
00:34
And therefore that is less than mg.
00:38
Therefore number one is true.
00:43
Let's move on to the next statement.
00:46
Statement to it says that water is removed from clothes in a spin dryer by centrifugal force.
00:55
That is correct because when something spins it experiences a centrifugal force which is outwards.
01:07
So therefore number 2 is true.
01:15
Now let's analyze statement number 3...
