Question

Forces 10N each inclined at 60°with each other what would be their resultant
​

Answer 1

Answer:

10√3  N

Explanation:

Resultant for vectors is given by √A² + B² + 2ABcosФ

Here,

A = B = 10N   , Ф = 60*

Therefore,

⇒ Resultant

⇒ √10² + 10² + 2(10)(10)cos60*

⇒ √100 + 100 + 200(1/2)

⇒ √100 + 100 + 100

⇒ √100*3

⇒ 10√3
