Answer:
The consecutive charge configuration has a more intense field than alternating
Explanation:
In each corner we place a different account there are only two different settings, see attached.
In the case of alternating charging (+ - + -) see diagram 1, the electric field in the center is canceled in pairs, resulting in a zero field
In the case of consecutive loads (+ + - -) in this case we have a result between the two charges, therefore the total field is
           E = 2 k q / ra2 a cos 45
The consecutive charge configuration has a more intense field than alternating
 
        
             
        
        
        
Answer:
Explanation:
Expression for velocity of wave produced in a hanging wire can be given  as follows 
Velocity v = 
where T is tension in wire and m is mass of wire per unit length.
In the given case 
T = Mg + mg
= Mg 
neglecting weight of rope 
mass of the rope per unit length
= m / L 
Velocity of wave 
 = 
=
