Question

The mass of a certain amount of salt determined
by two different persons was found to differ by
200 mg, one using the left pan for the weights
and the other using the right pan. Which of the
following statement is false?


(a). There is a zero error in the balance
(b). The true mass of salt is the mean of the two weighings
(c). The true mass is 100mg less than the higher value.
(d). The true mass is 200 mg more than the lower value.​

Answer 1

Answer:

There is a zero error in the balance

The true mass of is the mean of the two weighings

The true mass is 100 mg less than the higher value.

The true mass is 200 mg more than the lower value.

Answer :

D

Solution :

l1:l2=2:3

g1:g2=3:2

T1T2=l1/l1−−−−√l2/l2−−−−√=49−−√

T1T2=49−−√=23:f1f2=3:2
