Question

A book whose mass is 2 kg rests on a table. Find the magnitude of force exerted by the table on the book solution

Answer 1

Answer:

mass = 2kg

force exerted by table on a book = normal force by the surface .

F = mg

when g = 9.8

F = 2 x 9.8

F = 19.6 N

or,

when g = 10 m/s2

F = 2 x 10

F = 20 N

Answer 2

Answer:

19.6N or 20N (see below the conditions)

Explanation:

F = mg = 2×9.8 = 19.6N

(if g = 9.8 m/s²)

If g = 10 m/s²,

mg = 2×10 = 20N

By the way, it is Physics, from the topic Force.
