We know:
Formula for escape velocity is:
V = √(2GM/R)
where,
G = Universal gravitational Constant = 6.67 * 10^(-11) Nm^2/Kg^2
M = Mass
R = Radius
So, we get, using given values:
Given:
m= 1 * mass of Sun = 1.9891*10^30 kg
R = 150 * Radius of Sun = 695500km
v = √(2*6.67*10^(-11) * 1.9891*10^30kg/695500000m)
so, v = 617671.632719m/s
