In the circuit shown in Fig. 4.41, calculate the current in each resistor and potential difference across each resistor.

Text Solution

Verified by Experts

The correct Answer is:
(B)
Impulse `=` Change in momentum `= 1(4hat(i) + hat(j)) - 1 (6hat(i) + hat(j)) = -2hat(i)`
Which is perpendicular to the wall.
Component of initial velocity along `hat(i) = 6hat(i) rArr` Speed of approach `= 6 m//s`
Similarly speed of separation `= 4 ms^(-1) rArr e = (4)/(6) = (2)/(3)`
