In experiment of a-scattering if thickness of foil is changed from `2xx10^(-7)m` to `2.5xx10^(-6)` m what will be increase in number of `alpha`- particle scatered ?

A

about 12 times

B

100 times

C

remain constant

D

10 times

Text Solution

Verified by Experts

The correct Answer is:
A
about 12 times
Thickness of foil a number of a-particles (N)
`Nalphat`
`:.(N_(2))/(N_(1))=(t_(2))/(t_(1))=(2.5xx10^(-6))/(2xx10^(-7))=12.5=12`

During Searle's experiment, zero of the Vernier sacle lies between 3.20 xx 10^(-2), and 3.25 xx 10^(-2)m of the main scale. The 20^(th) division of the Vernier scale exactly coincides with one of the main scale divisions. When an additional load of 2kg is applied to the wire, the zero of the vernier scale still lies between 3.20 xx 10^(-2), and 3.25 xx 10^(-2)m of the main scale but now the 45^(th) division of Vernier scale coincide with one of the main scale divisions. the length of the thin metallic wire is 2m and its cross-sectional ares is 8 xx 10^(-7)m^(2) . the least count of the Vernier scale is 1.0 xx 10^(-5)m . the maximum percentage error in the Young's modulus of the wire is
