I e https://www webassign.net/web/Student/As: dla search O The acceleration is directed upward. O The acceleration is directed downward. O There is no acceleration An 8.61-kg point mass and a 15.7-kg peint mass are held in place 50.0 cm apart. A particle of mass m is released from a point between the two masses 20.0 cm from the 8.61-kg mass along the line connecting the two fixed masses. Find the magnitude and direction of the acceleration of the particle. 22 pelnts mass of venus es B1.5% that of the earth. and ts radius is 94.9% that of t he earth, (a) Compute t acceleration dus to gravity on the tarth.) the acceleration due to gravity on the surface of Venus from these data.

Explanation / Answer

force on one poimt charge due to another,

F = G M m / d^2

Fnet = G m (m1 / d1^2 - m2 / d^2)

and a = Fnet / m = G (m1 / d1^2 - m2 / d^2)

= (6.67 x 10^-11) [ (8.61 /0.20^2 ) - (15.7/0.30^2)]

= 2.72 x 10^-9 m/s^2 ..........Ans

direction = towards 8.61 kg mass
