Q1: Using the known values of the mass of the earth and the radius of the earth, calculate the value of g.

The radius of the Earth is 6.37 × 106 m

The mass of the Earth is 5.96 × 1024 kg

G = 6.67259 x 10-11 N m2

/kg2

the universal gravitation constant
.

Q2: What is the change in g if the measuring apparatus is raised in height by 1 meter?​

An electron and a proton are held on an x axis, with the electron at x = + 1.000 m and the proton at x = - 1.000 m. part a how much work is required to bring an additional electron from infinity to the origin? express your answer with the appropriate units. part b if, instead of the second electron coming in from infinity, it is initially at x = + 20.00 m on the axis and is given an initial velocity of 100.0 m/s toward the origin, does it reach the origin? part c how close to the origin does it come?
