A 5 kg sphere is accelerated upward by a string whose breaking strength is 200 N. The maximum value of acceleration with which the sphere can move without breaking the string is (take acceleration due to gravity. g = 10 m/s2)?

50 m/s²
30 m/s2
10 m/s2
20 m/s2

Option 2 : 30 m/s2

Concept:

Tension in the cord is given by

T = mg + ma

Where m = mass of sphere, g = acceleration due to gravity, a = maximum value of acceleration

Calculation:

Given:

m = 5 kg, T = 200 N, g = 10 m/s²

T = mg + ma

200 = 5 × 10 + 5 × a

a = 30 m/s²

Consider the string abbccddeee. Each letter in the string must be assigned a binary code satisfying the following properties: 1. For any two letters, the code assigned to one letter must not be a prefix of the code assigned to the other letter. 2. For any two letters of the same frequency, the letter which occurs earlier in the dictionary order is assigned a code whose length is at most the length of the code assigned to the other letter. Among the set of all binary code assignments which satisfy the above two properties, what is the minimum length of the encoded string ?
