A person standing on the surface of the earth has a weight of 650 N. What is its weight at a distance of two earth radii from th
snow_lady [41]

Answer:

72.22 N

Explanation:

F = weight

m = mass of body

M = mass of earth

R = radius of earth

G = universal constant of gravitation

F_1= 650 N

F_1 = GMm/R^2

two earth radius above the surface of the earth:

F_2=  GMm/(3R)^2=  GMm/9R^2= F_1/9= 650/9

=72.22 N

What is the potential energy at the origin due to an electric field of 5 x 10^6 N/C located at x=43cm,y=28cm?
Fudgin [204]

Answer:

potential energy at origin is 2.57*10^{6} volt

Explanation:

given data:

electric field E = 5*10^{6} N/C

at x = 43 cm, y = 28 cm

distance btween E and origin

\Delta r = \sqrt{43^2 +28^2}

\Delta r = 51.313 cm

potential energy per unit charge \Delta V = - Edr

\Delta V = 5*10^6*51.313*10^{-2} J/C

\Delta V  =  2.57*10^{6} volt

potential energy at origin is 2.57*10^{6} volt
