Answer:
The difference in the length of the two rods when compressed is .
Explanation:
Given that,
Length = 0.780 m
Diameter = 1.50 cm
Force = 4350 N
(a). For steel rod
We know ,
The young modulus for steel rod
Using formula of young modulus
(b). For copper rod
We know ,
The young modulus for steel rod
Using formula of young modulus
The difference in the length of the two rods when compressed is
Hence, The difference in the length of the two rods when compressed is .
A is negatively charged and b is positively charged a is larger than that on b
