Answer:
The Flemings left hand rule is used to find the magnitude of a magnetic force
Explanation:
Fleming's left hand rule states that if the first three fingers are held mutually at right angles to one another, then the fore finger points into the direction of magnetic field the middle finger in the direction of current while the thumb points in the direction of force.
Mathematically
Magnetic Force F= BILsinθ
Where
B= magnetic field density Tesla
I= current
L= length of conductor
θ= angle of conductor with field

Answer:
False
Explanation:
We know that if path difference is even multiple of wavelength then bright fringes are formed and if path difference is odd multiple of wavelength then dark fringes are formed .
For bright fringes
Path difference Δx = m λ
m = 0 , 2 , 4 , 6.......
If m = 2 then the path difference will be
Δx = 2 λ
therefore the above statement if false.
False
Answer:
This is so confusing I tried solving but didn't understand it
