Answer:
θ = sin⁻¹
Explanation:
From one of the equations of motion, v² = u² + 2as.......... equation 1
Since the object thrown was moving against gravity, then the acceleration, a would change to -g and the initial velocity u would change to V₀ sin θ because the object is travelling at angle of θ to the horizontal. By inputting all these parameter into equation 1, we would arrive at:
v² = (u sin θ)² - 2gd
(u sin θ)² = 2gd
d = (u sin θ)²/2g
sin² θ = 2gd
sin θ =
θ = sin⁻¹
Answer:
Maximum angle = 3.43⁰
Explanation:
Say that you are given the following information:
vertical distance between the charge plate = 0.03 m
length of the plate = 0.5 m
velocity of the electrons = 5 × 10⁶ ms⁻¹
the maximum angle is given by the formula:
where d = vertical distance between the charge plate
l = length of the plate
substituting the values l and d gives:
maximum angle,
= 3.43⁰
