A student determined Young's Modulus of elasticity using the formula , The
value of is taken to be
, without any significant error, his observation are as following,
Physical Quantity | Least count of the Equipment | Observed Value |
Mass (M) | ||
Length of bar(L) | ||
Breadth of bar(b) | ||
Thickness of bar(d) | ||
Depression |
Then the fractional error in the measurement of Y is :
Option: 1
Option: 2
Option: 3
Option: 4
