Question

Two forces F and 2F act on a particle. If the first force is increased by 12kN and

the second force is doubled, the direction of their resultant remains unchanged.

Find the value ​

Answer 1

Question :-

Two forces F and 2F act on a particle . if the first force increased by 12 N and the second force is doubled the direction of their resultant remains unchanged .find value

Answer :-

→ F = 20 for which resultant force remains unchanged .

Solution :-

According to the question ,

We have two forces F and 2F which act on a particle ,

→ First force is increased by 12 N ,

because resultant force remains equal ,so means that both are in opposite direction .

We have two forces F and 2 F ,

initial resultant force is -

→ 2F - F = F

now ,forces changed to double and 2F + 20

• ° • Final resultant force is -

→( 2F + 20 ) - 2F = 20 ( remains equal )

so , according to the question , resultant force is unchanged .

hence , F = 20 N .
