Answer:
T = 51.6 N
Explanation:
We know that maximum tension in vertical circular motion is at the bottom position and thus;
T − Mg = F_c = Mv²/r
Where F_c is centripetal force
Since T − Mg = Mv²/r
Let's make T the subject;
T = Mg + Mv²/r
Where;
T is tension of the string
M is mass of stone
v is speed of stone
r is length of chord
g is acceleration due to gravity which is 9.8 m/s²
From the question,
M = 2Kg
v = 4 m/s
r = 1m
Plugging in the relevant values we can obtain T;
T = M(g + v²/r) = 2(9.8 + 4²/1)
T = 2(9.8 + 16)
T = 51.6N
