mass of book=5kg
Then force exerted by earth on book= mg=5×9.8=49 N
External force exerted on book = 10
By Newton's third law of motion we get,
Force exerted by table on book= mg+10=49+10=59N
Hence force exerted by table on book = 59 N
Then force exerted by earth on book= mg=5×9.8=49 N
External force exerted on book = 10
By Newton's third law of motion we get,
Force exerted by table on book= mg+10=49+10=59N
Hence force exerted by table on book = 59 N

10+5g=N
10+(5×9.8) =N
10+49=N
N= 59N
