❥ Question :
ᴀ ʙᴏx ᴏꜰ ᴍᴀꜱꜱ 10 ᴋɢ ʜᴀꜱ ᴀ ʙᴀꜱᴇ ᴀʀᴇᴀ ᴏꜰ 100 Cᴍ ꜱQᴜᴀʀᴇ.ᴡʜᴀᴛ ɪꜱ ᴛʜᴇ ᴘʀᴇꜱꜱᴜʀᴇ ᴇxᴛʀᴀᴄᴛᴇᴅ ʙʏ ɪᴛ ᴏɴ ᴛʜᴇ ɢʀᴏᴜɴᴅ ?
❥ To Find :
ᴘʀᴇꜱꜱᴜʀᴇ
❥ Formula Used :
- ᴘʀᴇꜱꜱᴜʀᴇ = ꜰᴏʀᴄᴇ/ᴀʀᴇᴀ ᴏʀ ᴡᴇɪɢʜᴛ/ᴀʀᴇᴀ
- ᴡᴇɪɢʜᴛ = ᴍᴀꜱꜱ × ᴀᴄᴄᴇʟᴇʀᴀᴛɪᴏɴ ᴅᴜᴇ ᴛᴏ ɢʀᴀᴠɪᴛʏ
❥ Answer :
ᴡᴇɪɢʜᴛ = ᴍᴀꜱꜱ × ᴀᴄᴄᴇʟᴇʀᴀᴛɪᴏɴ ᴅᴜᴇ ᴛᴏ ɢʀᴀᴠɪᴛʏ
ᴡᴇɪɢʜᴛ = 10kg × 9.8m/s²
ᴡᴇɪɢʜᴛ = 98kgm/s²
→ We know N = kgm/s²
ᴡᴇɪɢʜᴛ = 98kgm/s²
ᴡᴇɪɢʜᴛ = 98N
ᴘʀᴇꜱꜱᴜʀᴇ = ᴡᴇɪɢʜᴛ/ᴀʀᴇᴀ
ᴘʀᴇꜱꜱᴜʀᴇ = 98N/100 cm²
ᴘʀᴇꜱꜱᴜʀᴇ = 98N/0.01 m²
ᴘʀᴇꜱꜱᴜʀᴇ = 0.98Nm⁻²
ᴘʀᴇꜱꜱᴜʀᴇ = 0.98Pa
