Some Important Questions Based on Physics Formulas Class 11th
Some of the important questions based on Topic-wise Physics Formulas Class 11th are given below. Students can practise them to get an idea of what questions are asked in the exam. This helps in better scores.
Question 1: A car accelerates uniformly from rest to a speed of 25 m/s in 10 seconds. Calculate its acceleration.
Solution: Given:
- Initial velocity, u=0u = 0u=0 m/s
- Final velocity, v=25v = 25v=25 m/s
- Time, t=10t = 10t=10 s
Using the formula a=v−uta = frac{v - u}{t}a=tv−u:
a=25−010=2.5 m/s2a = frac{25 - 0}{10} = 2.5 text{ m/s}^2a=1025−0=2.5 m/s2
Question 2: A stone is thrown vertically upwards with a velocity of 20 m/s. Calculate the maximum height reached by the stone.
Solution: Given:
- Initial velocity, u=20u = 20u=20 m/s (upwards)
- Acceleration due to gravity, g=9.8g = 9.8g=9.8 m/s2^22
At maximum height, final velocity v=0v = 0v=0 m/s. Use the formula v2=u2+2asv^2 = u^2 + 2asv2=u2+2as, where a=−ga = -ga=−g:
0=(20)2−2⋅9.8⋅s0 = (20)^2 - 2 cdot 9.8 cdot s0=(20)2−2⋅9.8⋅s
Solving for sss:
s=(20)22⋅9.8=20.41 ms = frac{(20)^2}{2 cdot 9.8} = 20.41 text{ m}s=2⋅9.8(20)2=20.41 m
Question 3: A ball is dropped from a height of 50 m. Calculate its velocity just before it hits the ground.
Solution: Given:
- Initial height, h=50h = 50h=50 m
- Acceleration due to gravity, g=9.8g = 9.8g=9.8 m/s2^22
Using the formula v2=u2+2asv^2 = u^2 + 2asv2=u2+2as, where u=0u = 0u=0:
v2=2⋅9.8⋅50v^2 = 2 cdot 9.8 cdot 50v2=2⋅9.8⋅50 v=2⋅9.8⋅50=980=31.3 m/sv = sqrt{2 cdot 9.8 cdot 50} = sqrt{980} = 31.3 text{ m/s}v=2⋅9.8⋅50=980=31.3 m/s
Question 4: A force of 10 N acts on a body of mass 5 kg for 2 seconds. Calculate the change in momentum of the body.
Solution: Given:
- Force, F=10F = 10F=10 N
- Mass, m=5m = 5m=5 kg
- Time, t=2t = 2t=2 s
Change in momentum Δp=F⋅tDelta p = F cdot tΔp=F⋅t:
Δp=10⋅2=20 kg m/sDelta p = 10 cdot 2 = 20 text{ kg m/s}Δp=10⋅2=20 kg m/s
Question 5: An object of mass 2 kg is moving with a velocity of 3 m/s. Calculate its kinetic energy.
Solution: Given:
- Mass, m=2m = 2m=2 kg
- Velocity, v=3v = 3v=3 m/s
Kinetic energy K.E.=12mv2K.E. = frac{1}{2}mv^2K.E.=21mv2:
K.E.=12⋅2⋅(3)2=9 JK.E. = frac{1}{2} cdot 2 cdot (3)^2 = 9 text{ J}K.E.=21⋅2⋅(3)2=9 J
Question 6: Calculate the gravitational force between two objects of masses 5 kg and 3 kg placed 10 m apart. Given G=6.67×10−11G = 6.67 times 10^{-11}G=6.67×10−11 N m2^22/kg2^22.

- Mass 1, m1=5m_1 = 5m1=5 kg
- Mass 2, m2=3m_2 = 3m2=3 kg
- Distance, r=10r = 10r=10 m
- Gravitational constant, G=6.67×10−11G = 6.67 times 10^{-11}G=6.67×10−11 N m2^22/kg2^22
Gravitational force F=G⋅m1⋅m2r2F = frac{G cdot m_1 cdot m_2}{r^2}F=r2G⋅m1⋅m2:
F=6.67×10−11⋅5⋅3(10)2=1.001×10−10 NF = frac{6.67 times 10^{-11} cdot 5 cdot 3}{(10)^2} = 1.001 times 10^{-10} text{ N}F=(10)26.67×10−11⋅5⋅3=1.001×10−10 N
