Answer:

Hold the balloon (negatively charged) just above your head so your hair (positively charged) will be attracted to it and stand up on end. ... The can will start to roll towards the balloon without touching it. The negatively charged balloon repels the electrons of the can so that a positive charge is near the balloon.

The planet Venus has a mass of 4.87 × 1024 kg and a radius of 6.05 × 106 km. What is the magnitude of the gravitational force th
Anastasy [175]

Answer:

7.2 x 10⁻⁶N

Explanation:

Given parameters:

Mass of Venus  = 4.87 x 10²⁴kg

Radius  = 6.05 x 10⁶km = 6.05 x 10⁹m

Mass of person  = 81kg

Unknown:

Gravitational force  = ?

Solution:

To solve this problem, we use the Newtons law of universal gravitation:

  Fg  = \frac{G x mass of venus x mass of person}{radius^{2} }  

G is the universal gravitation constant  = 6.67 x 10⁻¹¹

 Fg  = \frac{6.67 x 10^{-11}  x 4.87 x 10^{22} x 81 }{(6.05 x 10^9)^{2} } }

 Fg  =  7.2 x 10⁻⁶N
