Answer:
Staying the same unless, another force acts upon it
Explanation:
An object will stay still or keep moving at the same pace and in a straight line until acted upon by an external force that is unbalanced.
Mass of the Earth = 5.972 x 10²⁴ kg
Mass of the asteroid = 1 x 10⁹ kg
Separation distance = 3 x 10⁶ m (between the Earth's center and the asteroid's center)
Gravitational force between two masses =
(6.67 x 10⁻¹¹ nt-m²/kg²) · m₁ · m₂ / (distance)²
= (6.67 x 10⁻¹¹ nt-m²/kg²) · (5.972 x 10²⁴ kg) · (1 x 10⁹ kg) / (3 x 10⁶ m)²
= (6.67 · 5.972 / 9) x 10¹⁰ · (nt · m² · kg · kg / kg² · m²)
= 13.28 x 10¹⁰ newtons
= 132.8 Giga-newtons .

Explanation:
It is given that,
Length of wire, l = 0.53 m
Current, I = 0.2 A
(1.) Approximate formula:
We need to find the magnitude of the magnetic field made by the current at a location 2.0 cm from the wire, r = 2 cm = 0.02 m
The formula for magnetic field at some distance from the wire is given by :
B = 0.000002 T
(2) Exact formula:
B = 0.00000199 T
or
B = 0.000002 T
Hence, this is the required solution.
