The category is "Dwarf Planet" .
Answer: Image for option 4
Explanation:
The fourth option is correct because there are three forces acting on the block:
which is the <u>Friction force</u> and acts against the movement of the block
the <u>Normal Force</u>, which is perpendicular (normal) to the surface of the rough ramp
the Weight of the block, which is the force due gravity acceleration and has an <em>x-component</em> and an <em>y-component.</em>
Answer:
Explanation:
given,
charge of two spherical drop = 0.1 nC
potential at the surface = 300 V
two drops merge to form a single drop
potential at the surface of new drop = ?
r = 0.003 m
volume =
=
= 2.612 × 10⁻⁷ m³
R = 0.00396 m
