Question
The adjacent graph shows the extension (ᐃl)of a wire of length 1m supemded from the top of a roof at one end and with a load W connected to the other end. If the cross-sectional area of the wire is 10-6 m2, calculate the young′s modulus of the material of the wire.
Options
A.2 × 1011 N/m2
B.2 × 10-11 N/m2
C.3 × 10-12 N/m2
D.2 × 10-13 N/m2
= 20 × 1011 N/m2More Photoelectric Effect Questions
