Find the phase and the missing properties of p, t, v, u, and x for water at1. 500 kpa, 100°c2. 5000 kpa, h = 1800 kj/kg3. 5000 kpa, u = 2950 kj/kg4. −6°c, v = 1 m3/kg.

initial speed when it is dropped is 150 ft/s

now at the same moment the acceleration due to gravity is perpendicular to its velocity

so as we know that

now we have centripetal acceleration a = 32 ft/s^2 as its perpendicular to velocity

while tangential acceleration at the same moment will be zero

so

now radius of curvature is given as

so the radius of curvature just after it is dropped is 703.125 ft

electric field is a function of 1/r^2

yes, the force per unit charge for a point charge is inverse square law.
