By what factor would a person’s weight be increased if Earth had 10 times its present mass, but the same volume?
Dafna1 [17]

Answer:

10 times

Explanation:

The weight of the person is defined as the product of mass of person and the acceleration due to gravity of that planet.

Let the gravity is g.

W = m x g     .... (1)

Now the value of g depends on the mass of earth when the radius of earth is constant.

g' = 10 g

So, W'  = m x g' = m x 10 g = 10 mg = 10 W     (from (1)

So, the weight of the person becomes 10 times.

Three point charges, -4.7 x 10-9 C, -9.7 x 10-9 C, and 7.2 x 10-9 C, are fixed at different positions on a circle. The total ele
irinina [24]

Answer:

Explanation:

q1 = - 4.7 x 10^-9 C

q2 = - 9.7 x 10^-9 C

q3 = 7.2 x 10^-9 C

Potential at the centre of the circle, V = - 1900 V

Let the radius of the circle is r.

So, the potential is given by

V = \frac{Kq_{1}}{r}+\frac{Kq_{2}}{r}+\frac{Kq_{3}}{r}

- 1900 = \frac{9\times 10^{9}}{r}\left ( - 4.7 - 9.7 + 7.2 \right )\times 10^{-9}

- 1900 = \frac{-9\times 7.2}{r}

r = 0.034 m = 3.4 cm
