Answer:
Given:
A is directly proportional to R2
R is inversely proportional to T
Formula:
If x is directly proportional to y, then x α y
If x is inversely proportional to y, then x α 1/y
Calculation:
A α R2 ----(1)
R α 1/T
⇒ R2 α 1/T2 ----(2)
From equation (1) and equation (2)
A α 1/T2
⇒ A = k/T2 (K = constant)
100 = k/52
⇒ 100 = k/25
⇒ k = 100 × 25
⇒ k = 2500
Again,
A = k/T2
200 = 2500/T2
⇒ T2 = 2500/200
⇒ T2 = 25/2
⇒ T = √25/2
⇒ T = 5/√2

Answer:
Answer:
Given:
A is directly proportional to R2
R is inversely proportional to T
Formula:
If x is directly proportional to y, then x a y
If x is inversely proportional to y, then x a 1/y
Calculation:
A a R2
Ra 1/T
→ R2 a 1/T2
----(2)
From equation (1) and equation (2)
A a 1/T2
→ A = k/T2
100 = k/52
→ 100 = k/25
→ k = 100 x 25
→ k = 2500
----(1)
V
(K = constant)
From equation (1) and equation (2)
A a 1/T2
→ A = k/T2
(K = constant)
100 = k/52
→ 100 = k/25
→ k = 100 × 25
→ k = 2500
Again,
A = k/T2
200 = 2500/T2
→ T2 = 2500/200
→ T2 = 25/2
→ T = √25/2
→ T = 5/√2
