Question

the ratio of the number of factors of n and 5n is 1:2. What is the ratio of number of factors of 5n and 25n​

Answer 1

Answer:

Step-by-step explanation:

Let A and B be the two forces.  

Then A=3 x,B=5 x;R=28 N and θ=60  

o

.  

Dividing A by B,  

B

A

​

=  

5

3

​

 

We know that R=  

a  

2

+B  

2

+2 AB cosθ

​

 

⇒28=  

(3 x)  

2

+(5 x)  

2

+2(3 x)(5 x)cos 60  

o

 

​

 

=  

9 x  

2

+25 x  

2

+15 x  

2

 

​

=7 x

⇒x=  

7

28

​

=4

Hence, forces are A=3×4=12 N,B=5×4=20 N
