    v1 is greater than v2 cox V is directly proportional to R. n the resistance ov the parallel combination of 6 n 3 ohms is greater. i1 is greater cox if u suppose any value of V, n substitute it in the equation V=IR, u will get i1>i2

    x=(u^2)/2a 2a is constant so x is directly proportional to u^2 20% inc in speed is 6/5 u. new x= (6/5)^2

    i didnt understnd how u did it. bt mene phle 6 n 3 k parallel combination ka sum nikala that is 2 ohms. so the voltage will be 6v in d 2 ohm resistor. n 6v across d 6 n 3 ohm resistors respectively. we have the voltage n resistance. so v=ir, 6=6i. so current is 1A
