Coulomb's law, or Coulomb's opposite square law, is a trial law of material science that measures the measure of power between two stationary, electrically charged particles. The electric power between charged bodies very still is customarily called electrostatic power or Coulomb power.

Review Conceptual Example 7 before starting this problem. A uniform plank of length 5.0 m and weight 225 N rests horizontally on
Andreas93 [3]

Answer:

0.82 m

Explanation:

We are given that

Weight,w_1=225 N

Length,l=5 m

d=1.1 m

We have to find the distance x  for which person weighs 385 N walk on the overhanging part of the plank before it just begins to tip.

Half length=\frac{l}{2}=\frac{5}{2}=2.5 m

r=\frac{l}{2}-d=2.5-1.1=1.4 m

w_2=385 N

When system in equilibrium then

w_1r=w_2 x

225\times 1.4=385\times x

x=\frac{225\times 1.4}{385}

x=0.82 m

An object is placed 9.5 cm in front of a convex spherical mirror. Its image forms 3.2 cm behind the mirror. What is the radius o
o-na [289]

Using the mirror formula.

1/v + 1/u = 1/f

1/9.5 + 1/3.2 = 1/f

1/f = 3.2 + 9.5 / 9.5 * 3.2

1/f = 4.82 cm

Radius = 2f

Radius = 2 x 4.82

Radius = 9.64 cm
