Acharged box ( m = 495 g, q = + 2.50 μ c ) is placed on a frictionless incline plane. another charged box ( q = + 75.0 μ c ) is fixed in place at the bottom of the incline. if the inclined plane makes an angle θ of 35.0 ∘ with the horizontal, what is the magnitude of the acceleration of the box when it is 61.0 cm from the bottom of the incline?
