Question

. A 100.0 N ball has three forces acting on it (see the "force space" illustration at the right, drawn to scale). The ball is in equilibrium. Force C is a gravitational force ( 100 N). .Force A and force B are 90.0° apart. Force A is about 26.60 above the horizontal. The grid lines shown represent increments of exactly 10 N. What is the magnitude of force A? a. 1000N b. 2000 N c. 4000N d. 8000 N Determine the sum with the correct number of significant figures: (1.234 x 101) (1.23 x 102? a. 1.246 x 10 b. 2.464 x 10 c. 1.357 x 10 d. 2.4640 x 10' e. 1.36 x 10

Explanation / Answer

A) Coordinates of A=(-40,20) as each grid increment means 10N

Therefore, magnitude of Force= sqrt (xcomp)^2 + (ycomp)^2

Force= sqrt(-40)^2 + (20)^2

Force=sqrt(2000) N =option b

=========

B) (1.234*10^4) + (1.23*10^2)

=12463=1.246*10^4 =option a
