Question

2forces p and 2p if first be double and second increase by 20 then what will be no change in direction of the resultant find p. ?​

Answer 1

Answer:

If the direction of the resultant force does not change, it means the angle between them remain the same.

Assuming the angle was initially 45 degrees, it will remain the same

tan45  

0

=  

2P

2P

​  

=1  

Now, first force is double

So, force =4P

20 N is added to the second force

Then, force =2P+20

Now,

 tan45  

0

=  

2P+20

4P

​  

 

 

2P+20

4P

​  

=1

2P=20

P=10N

Hence, this is the required solution
