Question

A 2.00lb physics book rests on an ordinary scale that is placed on a horizontal table.

The reaction force to the downward 2.00lb force on the book is?

Answer 1

A.an upward 2.00lb force on the scale due to the table.
B.an upward 2.00lb force on the book due to the scale.
C.an upward 2.00lb force on the table due to the floor.
D.an upward 2.00lb force on the earth due to the book.

Answer 2

I think it is B....

Answer 3

when you place a book on the scale the reaction force acting on the book would be upward due to the scale but not the table.

Answer 4

so yes it is B.

Answer 5

i just tried it and b is wrong

Answer 6

is it the pic of your question?

Answer 7

no picture but thats what I got out of it...

Answer 8

no, I am right. The reaction force due to the downward 2.00lb force on the book is an upward 2.00lb force on the book due to the scale.

Answer 9

no....that answer is wrong. I already tried submitting it.

Answer 10

I think it is a very poorly conceived question.
Physics is tricky enough to learn even when you have good teaching, this kind of question helps no one.

What does the scale look like, exactly ? Each part of the system experiences an interaction with each of the other parts.

Very poor question.

Answer 11

I'm not criticising you, mkmalik, by the way, but whoever it was that dreamt up this question in the first place : )
