As we know that gravitational force of Sun will provide the centripetal force to all planets
so here we will have


here we know that



now from above equation




Answer:
The electromagnetic force.
Answer:
a)θ=74.03° (N-E)
b)t=1.56 hr
Explanation:
Given that
Plane speed = 200 km/h
Wind speed = 55 km/h
Now from diagram
V is the resultant velocity of plane

V=192.28 km/h towards north
From triangle ABC

θ=74.03°
Given that
d=300 km
We know that
d = V x t
300 = 192.28 x t
t=1.56 hr
