If the magnitude of a positive charge is tripled, what is the ratio of the original value of the electric field at a point to the new value of the electric field at that same point?
a) 1: 2
b) 1: 3
c) 1: 6
d) 1: 9

b)1 :3

Explanation:

Lets that

The value of a positive charge = q

As we know that electric filed on a point charge given as

Where ,K=Constant

q=Charge ,r=Distance

If the value of the charge gets tripled ,q'= 3 q

Then electric filed E'

E' = 3 E

Therefore we can say that

therefore the answer will be --

b)1 :3

100 cents = 1$

Explanation:

1 penny is the same as 1 cent so 100 pennys would = 1 dollar hopes this helps.
