Answer:
The magnitude of the electrostatic force is
Explanation:
Given that,
Charge
Charge
Distance = 2.40 m
We need to calculate the electrostatic force
Using formula of electrostatic force
Where, k = coulomb's constant
q = magnitude of the charge
d = distance
Put the value into the formula
Hence, The magnitude of the electrostatic force is
Answer:
Explanation:
Given
Weight of helicopter
inclination of blades with vertical
Suppose is the lifting Force
Now using F-B-D
as helicopter is moving with constant velocity
balancing forces in Vertical Force
Now sin component of lift is air resistance
where R=air resistance
C.figure 3 is the answer had the same and got is right
