Physics: Post your doubts here!
At highest point, vertical comp of velocity is zero and horizontal comp is v cos45= 0.707v New kinetic energy= 0.707²= 0.50E -

I think that it is the lower one wire which is at zero potential -

The switch is always connected to the positive terminal of the battery so C and D are ruled out We need a voltage between 5 and 7V so if we look at A, the output is 1/2 x 9= 4.5V which is not bw the specified range In B the output is 2/3 x 9= 6V which is within the range so B is the correct option -

Is this statement regarding 1% correct?? But the extra 0.1 is 10%, not 1% -

For fx although there are 2 antinodes but u can see in the diagram that it is 1 cmplt loop which means it is equal to half a wavelength -

1 closed loop is half of wavelength we have read this during our course In this diagram, there are 3 closed loops and 2 halves making a total of 4 complete loops...thus that is 2λ -

U first try with 1 node then with 2 etc but the wavelengths for those are not in the options They are 200cm, 100cm 66.67cm and 50cm respectively -

1 is a positive value of n...but if we use D for the 1st dark fringe, the path diff would be 1.5λ which is not correct...it should be 0.5λ
