Answer:
A) 7×10⁻⁸ N
Explanation:
r = Distance between the two skaters = 2 m
m₁ = m₂ = Mass of the two skaters = 65 kg
G = Gravitational constant = 6.67 × 10⁻¹¹ m³/kgs²
From Newton's Law of Universal gravity
∴ Force of gravity between the two skaters is 7×10⁻⁸ N
Answer:
U = - 4 x
Explanation:
ΔV = potential difference = Volts
q = charge on electron = C
electric potential energy is given as
U = q ΔV = ( ) (
)
= - 4 x
