Answer:
Explanation:
Capacitance of capacitor
= ε₀ A / d , ε₀ is permittivity of space , A is area of plate , d is distance between plates.
= 8.85 x 10⁻¹² x 2 x 10⁻³ / (6 x 10⁻³)
= 2.95 x 10⁻¹² F
Electric field E = V / d , V is potential difference
V = E x d
= 100 x 10³ x 6 x 10⁻³
= 600 V
Charge on the capacitor
= capacitance x potential difference
= 2.95 x 10⁻¹² x 600
= 17.7 x 10¹⁰ C
Answer
given,
mass = 100 kg
acceleration = 10 m/s²
A mass 20 kg slides over 100 kg block
acceleration = 3 m/s²
horizontal friction exerted by the 100 kg block on 20 kg
using newton's second law
F - f = 0
F = f
f = ma
f = 20 × 3
f = 60 N
now net force acting on the 100 kg block
F_net = m a
F_net = 100 x 10
F_net = 1000 N
after 20 kg block falls the acceleration of the bock
F = 1000 +60
F = 1060 N
acceleartion on the block


a = 10.60 m/s²
