QJEEM21Phdf1d: JEE Main 2021 Physics - Class 11 JEEM21Phdf1d Solution: Statement : 1 If three forces F → 1 , F → 2 and F → 3 are…

Statement : 1

If three forces

{\vec{F}}_{1}, {\vec{F}}_{2}

and

{\vec{F}}_{3}

are represented by three sides of a triangle and

{\vec{F}}_{1} + {\vec{F}}_{2} = - {\vec{F}}_{3}

, then these three forces are concurrent forces and satisfy the condition for equilibrium.

Statement : 2

A triangle made up of three forces

{\vec{F}}_{1}

,

{\vec{F}}_{2}

and

{\vec{F}}_{3}

as its sides taken in the same order, satisfy the condition for translatory equilibrium.

In the light of the above statements, choose the most appropriate answer from the options given below :

JEE Main 2021 (Online) 31st August Evening Shift Physics - Laws of Motion Question 70 English Explanation

Here,

{\vec{F}}_{1} + {\vec{F}}_{2} + {\vec{F}}_{3} = 0

{\vec{F}}_{1} + {\vec{F}}_{2} = - {\vec{F}}_{3}

Since

{\vec{F}}_{n e t} = 0

(equilibrium)

Both statements correct.
