Question

when two resistors R1 and R2 are connected in parallel, then their parallel combination is given by Rp=R1 R2/R1+R2. If error in measurement of R1 and R2 are ∆R1 and ∆R2 respectively then error in measurement of their parallel combination, that is ∆Rp is_
1)Rp^2(∆R1/R1^2+∆R2/R2^2)
2)Rp(∆R1/R1+∆R2/R2)
3)∆R1/R1+∆R2/R2​
