#"There are two force acting on body in different directions"#
#"First ,we have to find the vectorial sum of the two forces."#
#F_1= < -7,1 >" ; "F_2= <6,-3>#
#vec F_1= -7i+j" ; "vec F_2=6i-3j#
#vec F_R:"represents the vectorial sum of "vec F_1" and "vec F_2#
#vec F_R=(-7+6)i+(1-3)j#
#vec F_R=-i-2j#
#"now,we need to find the magnitude of "vec F_R#
#F_"net"=sqrt((-1)^2+(-2)^2)=sqrt(1+4)=sqrt5" "N#
#"We have to use the Newton's second law of motion :"#
#a:"represents the acceleration of object"#
#m:"represents the mass of object"#
#a=F_"net"/m#
#a=sqrt5/9" "m/s^2#
#"direction of acceleration is being shown in animation above."#
