Figure shows three resistor configurations R1,R2 and R3 connected to 3 V battery .

If the powers dissipated by the configuration R1,R2 and R3 are P1,P2 and P3, respectively, then

A

p1> p2 > p3

B

p1> p3 > p2

C

p2 > p1 > p3

D

p3> p2 > p1

Text Solution

Verified by Experts

The correct Answer is:
`4 m//s`
For collision between A & B
`v_(A) = ((m - 2m))/((m + 2m)) (9) = -3 ms^(-1)`
`v_(B) = (2(m))/((m + 2m))(9) = +6ms^(-1)`
For collision between B and C
`v_(c ) = ((2m)/(2m + m)) (6) = 4ms^(-1)`
