The charge is
Explanation:
Given that,
Distance = 2.5 mm
Electric field = 800 NC
Length
We need to calculate the linear charge density
Using formula of linear charge density
Put the value into the formula
We need to calculate the charge
Using formula of charge
Put the value into the formula
Hence, The charge is
Answer:
The final position made with the vertical is 2.77 m.
Explanation:
Given;
initial velocity of the ball, V = 17 m/s
angle of projection, θ = 30⁰
time of motion, t = 1.3 s
The vertical component of the velocity is calculated as;
The final position made with the vertical (Yf) after 1.3 seconds is calculated as;
Therefore, the final position made with the vertical is 2.77 m.
