Question

In Melde's experiment, when the wire is stretched by an empty pan, four loops are obtained and when a six-gram weight is added to the pan, the number of loops becomes one. The mass of pan is ______

Options

• 1.2 gram

• 1.5 gram

• 0.8 gram

• 0.4 gram

Answer 1

In Melde's experiment, when the wire is stretched by an empty pan, four loops are obtained and when a six-gram weight is added to the pan, the number of loops becomes one. The mass of the pan is 0.4 grams.

Explanation:

`P_1^2T_1 = P_2^2T_2`

16 × m = 1(m + 6)

16 m = 6

m = `6/15 = 0.4` gm
