Answer:
0.0567 N
Explanation:
q1 = 3 micro coulomb 
q2 = - 2 micro coulomb 
OB = 50 cm 
AB = 60 cm 
By using Pythagoras theorem in triangle OAB 


OA = 78.1 cm 
By using the Coulomb's law, the force on 3 micro coulomb due to -2 micro coulomb is 

F = 0.0885 N 
The horizontal component of force is 
= F CosФ = 
= 0.0885 x 50 / 78.1 = 0.0567 N
 
        
             
        
        
        
Answer:
15.13m
Explanation:
change 15m to cm
1m=100cm
15m times 100=1500cm
add 1500+13 = 1513cm
in metres it will be 15.13m

Answer:231.16 N/C
Explanation:
Given
Electric Flux
Area(A)
Given Field point above 
Therefore angle between Area vector Electric Field =90-31.6=
We know that Flux is given by 



E=231.16 N/C
 
        
             
        
        
        
Answer:
1 m = 39.37 in = 39.37/12 ft = 3.28 ft
V = 1145 k/hr  = 1145k/hr * 6076 ft/k = 6957020 ft / hr
V = 6957020 ft/hr / 3600 s/hr = 1933 ft/sec
V = 1933 ft/sec / (3.28 ft / m) = 589 m/s
Check:
88 ft/sec = 60 mph
(1145 k/hr * 6076 ft / k) 3600 sec/hr = 1933 ft/sec = 589 m/s
1933 ft/sec / (88 ft/sec) * 60 mph = 1318 mph
Also,  1318 / 1145 = 6076 / 5280       as it should
