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
Answer:
Displacement = 4000 m
Explanation:
Given that,
Each lap is 1000 m.
David completes 4 laps of his complex
We need to find David's displacement. In n laps, the net displacement is n time of distance covered.
Displacement = 4 × 1000
= 4000 m
Hence, Davis's displacement is 4000 m.
