Answer:

Explanation:
Let the length of the string is L. 
Let T be the tension in the string. 
Resolve the components of T. 
As the charge q is in equilibrium.
T Sinθ = Fe       ..... (1)
T Cosθ = mg     .......(2)
Divide equation (1) by equation (2), we get 
tan θ = Fe / mg 




As θ is very small, so tanθ and Sinθ is equal to θ.

Answer:
a)ΔV = 6.48 KV
b)ΔU =18.79 mJ
Explanation:
Given that
E= 1.8 KV/m
a)
We know that
Electric potential difference  ΔV given as
ΔV = E .d
Here 
E= 1.8 KV/m
d= 3.6 m
ΔV = E .d
ΔV = 1.8 x 3.6 KV
ΔV = 6.48 KV
b)
Given that
q=+2.90 µC
Change in electric potential energy ΔU given as
ΔU = q .ΔV

ΔU =18.79 mJ
  
        
             
        
        
        
Answer:
No, the car is decelerating  
Explanation:
No the car is decelerating if it exits a freeway and goes from 65
mph to 35 mph since the change in velocity is negative. 
change in velocity = final - initial
change in velocity  = 35 - 65
change in velocity = -30mph
Since the change in velocity is negative, hence the car is decelerating. Deceleration is a negative acceleration
