Explanation:
Below is an attachment containing the solution.
Answer:
it's B. circuit a and b are series circuit while c is parallel
Answer:
They are equal
Explanation:
angle of incidence = angle of reflection
Drag Force = bv^2 = ma; a = g = 9.81 m/s^2
b = mg/v^2 = (0.0023×9.81)/(9.4^2)
b = 0.000255
Electric field due to a point charge is given as

here we know that

also the distance is given as

now we will have

so we will have

so above is the electric field due to proton
