Question

parallelogram law is applicable only for 2/3/4/any no. of forces

triangle law is applicable only for 2/3/4/any no. of forces.

polygon law is applicable only for 2/3/4/any no.of forces

the resultant force of two coplanar collinear forces will be maximum when they act a. same direction, b. different direction, c.at a right angle, d. at an angle​

Answer 1

Answer:

2

2

any number of forccs

same direction

parallelogram law of vector addition is used to add two vector acting simultaneously at a point .

where as triangle law is used to add vectors acting in the same order .

polygons law of vector addition is used for add number of vector acting in the same order and the closing side represent the addition of the number of vector .

according to the formula of resultant vector R^2=A^2+B^2+2ABcosp

R is maximum when cosp is maximum

so cosp= 1 is the maximum value so p=0

so Aand B vector are in same direction
